This week Mrs.Hoffer taught me about Circumference. Circumference is an really easy lesson it’s two methods of doing it. The two methods have separate formulas to solve for Circumference problems. In my picture you see I have provided the two formulas and examples to go along with them. The first method and example I did was the circumference formula involving a radius. The second method and example I did was the circumference formula involving a diameter. Circumference is an really easy concept to learn. Mrs.Hoffer nailed her lesson spot on this week.

I’m going to tell you about my 2018 Christmas Break. I slept in and relaxed the first few days because I was exhausted from school and football workouts. I played my PS4 with my friends all night. I saw and spent some time with some of my middle school friends. On Christmas Day I woke up helped my little brothers open their presents and help them set up some of their toys. Then, I opened my presents I got some AirPods, new shoes , gold chain , and some money. Later on in the day some of my family gathered at my house and we ate an untraditional dinner for Christmas which was seafood. The food was delicious and everyone enjoyed themselves. On the last couple of days I worked out at the YMCA and went to some basketball games with my friends . That’s how my Christmas Break went.

This week in Mrs.Hoffer class we learned about Law of Cosines. Law of Cosines is similar to Law of Sines in a way but it’s a different scenario. When you’re doing Law of Cosines you have to determine whether it’s “SAS” or “SSS” before trying to solve the problem. Mrs.Hoffer taught a great lesson this week. I’m prepared for the Law of Sines/Cosines test now .

This week in Mrs.Hoffer class we learned about Law of Sines. Law of Sines is really the same as when she taught us Trigonometry Ratios but it just has more steps to it. Law of Sines is not hard it’s an easy concept. Mrs.Hoffer showed us some notes and gave great examples to teach the class how to do it. Mrs.Hoffer taught us how to do this in 1 day. Mrs.Hoffer is an great math teacher. That’s what we learned this week.

This week I’m going to tell you all what I’m thankful for. I am thankful that god allows me to play the game of football. I am thankful  that  god allows me to work my body hard and still stay healthy. God allows my body to grow and get bigger with all the weight lifting and conditioning. God allows me with great athletic ability, heart , determination and hard work ethic. That’s what I’m thankful for this Thanksgiving.

This week I’m going to show you how to do 2 problems off the study guide Mrs.Hoffer gave us. The first problem you have to use Inverse Trig. First, you have to label your triangle sides. Next, you have to write to the side the information you got from your triangle. Then, based on the formula you used you have to put the numbers in a fraction and divide.( Ex) sin-theta = opp over hyp. Then you put your opp first which was 15 over your hyp which was 24 then divide. Next , you get the answer from dividing and you get your calculator and the division answer then press 2nd then press sin-1 and round to the nearest 10th and that’s your answer. The Second problem I’m going to show you how to do is Trig with Pythagorean theorem. First, you label the triangle like you would normally do then make sure you put c wherever your hypotenuse is and it doesn’t matter where you put A and B. Next, you start your problem A2 + B2 = C2. Then you plug in 8 squared + 13 squared = c2. Then you add your numbers so you get 64 + 169=c squared. After you add your remaining numbers and get 233= C squared but you want to to get c by itself so you do the square root of 233 and C squared and your answer is 15.264.

This week I’m going to show you how to do two problems off of the test Trigonometry study guide. The first problem is that we have to find the measure of ( X ). You have to label your triangle sides first. Next, you write to the side what information you have from your labels. Then, you write the formula that you have after labeling and writing down the information from the triangle. Then, based on the formula you used you have to put the numbers in a fraction and divide it. (Ex.) sin-theta= opp over hyp. They you put your opp first which was 15 over your hyp which was 24 then you divide. Next, you get the answer from dividing and you get a calculator and put the division answer then press 2nd then press sin-1 and round to the nearest 10th and that’s your answer. The 2nd problem is very similar but instead you have to use the cosine formula. First you put your adj which is 8 over your hyp which is 11. Then, you divide and after you divide the answer you got from it round it to the nearest 10th, then after that put the answer in your calculator and press 2nd then cos-1 and get your answer round to the nearest 10th and that’s your final answer.

This week in Mrs.Hoffer class we learned about Inverse Trigonometry. Inverse Trigonometry is basically like regular Trig but you have to do an extra step or 2. Instead of finding ( X ) you’re finding the theta of the right triangle. This week lesson was really easy and fun. Mrs.Hoffer is an great teacher and explains her lesson well. This checks another lesson Mrs.Hoffer has taught me so far this year.
