Can someone help me with this?
1. For the point sqrt(2)/2, sqrt(2)/2 on the terminal side of an angle, determine trigonometric functions.
I have for this one: sin = sqrt(2)/2 csc = sqrt(2)
cos = sqrt(2)/2 sec = sqrt(2)
tan = 1 cot = 1
2.A park ranger needed to know the distance across a chasm at Bryce Canyon National Park. The ranger noted a tree on the edge of the chasm directly across from where she was standing. She walked 500 feet east along the edge of the chasm (on a line that was at a 900 angle from the line across the chasm) and then took a bearing to the tree. She found the bearing from her new position to the tree to be N300W.
What is the distance, in feet across the chasm (from her original position to the tree?
3. The point (15, 20) is on the terminal side of an angle drawn in standard position. Find the exact value of the cosine of the angle.
