11/29/18 Law of Sines

This week we learned about Trigonometry : the law of sines. I will be explaining number 2. The formula to set the problem up would be sin A / a = sin B / b. When you plug in your numbers you will get 40/sin 62 = x/sin 20. In this equation we will have […]

I am thankful for being a talented basketball player, my family, friends, to be able to have a house, and shoes and clothes. I am thankful for being a talented basketball player because some people wish that they could have the opportunity that I have. I am thankful for my family because they make a […]

11/15/18 Angle of Depression/Elevation

The first question says that a flag poll has the shadow of 23 foot long. With a angle of elevation of 44 degrees. I have to find the height of the flag pole. The opp is x, the adj is 23, and the theta is 44. The formula for this problem is tan(theta)=opp/adj. Then you […]

Study Guide Test 4 11/8/18

The past 2 weeks we learned about Pythagorean Theorem and Trigonometry. I will be doing number 3 on the Pythagorean Theorem worksheet. The formula at you will be using is a^2+b^2=c^2. The 3 sides that are given is 7 which is a, 9 which is c and x which is b. When you plug in […]

Inverse trig rations 11/1/18

This week we learned about inverse trig ratios. Inverse trig ratios help us find the missing angle. Trig ratios help us find the missing angle. To find the theta you have to have ^-1 at the end of formula. I am going to explain example 7. On example 7 you have to name your sides […]

Trigonometric Ratios 10/25/18

This week we learned about trigonometric ratios. In your right triangle across from the box is the hypotenuse and across from the theta is the opposite. The sine formula is opposite over hypotenuse. The formula for cosine is adjacent over hypotenuse. The formula for tangent is opposite over adjacent. The theta sign is the unknown […]

10/22/18 Pythagorean Theorem

This week we learned about Pythagorean Theorem. The formula for Pythagorean Theorem is a^2 + b^2 = c^2. The hypotenuse is the side opposite of the right angle. The legs are the sides adjacent to the right angle. The hypotenuse will be c and the legs will be a and b of the formula. In […]

10/8/18 major grade

This nine weeks we have learned about distance and midpoints, linear measure, and rotation. I will be explaining number 7 on the distance and midpoints worksheet. The question on the worksheet reads L(-7,0), Y(5,9). The formula you would use for this question is d square root of the second coordinate x minus the first coordinate […]

9/27/18 Rotations

This week we learned about rotations. There are two ways that you are able to rotate the shape, you can rotate the figure clockwise or counterclockwise. Clockwise is left and counterclockwise is right. You still are given the image in the problem so you would have to find the pre-image. When you have to rotate […]

9/20/18 Study guide questions

On our study guide I will be explaining number 2, you have to reflect over the y-axis. The rule is that you have to multiply the x-coordinate by -1. Your pre image points are A(3,-4) B(1,-6) C(-2,-3) and D(3,1). The y coordinates will stay the same. For A it would be (3•-1= -3,-4). For B […]
