Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the high temperature of 96 degrees occurs at 3 PM and the average temperature for the day is 80 degrees. Find...

Ok so on a math work sheet we had a problem where there was two side lengths of a triangle, 63 and 91. The third side was only described as being traveled across by a plane with an average of 300mph...

Find the solutions for the equation 7sin^2 theta - 9 cos2 theta = 0 for 0 < or equal to theta < 360 degree.

it says thats the answer i dont know how that is possible because cos24 = .9135... if thats the case what is cos28?

A survey team was to measure the distance across a river over which a bridge is to be built. They set up a survey post on their side of the river directly across from a large tree on the other side...

The height of a person above the ground on a Ferris wheel is given by the function h(t)=9 sin {pi/20 (t- pi/2))+ 12 where h(t) is the height in meters of person t seconds after getting on a)...

2cos(1/2x)-cos(1/2x)=0 , where 0<x<2pi determine the complete solution for the equation

A woman looks at a plane flying directly at her at a constant height and a speed. The plane is traveling 400mph. She first sees the plane at an angle of elevation of 6 degrees with the horizontal...
