Pre Calculas

Complete the identity sin theta / cos theta + cos theta / sin theta = ?


Do you mean
(sin theta/cos theta) + (cos theta/sin theta) ?
That would equal tan x + cot x = tan x + (1/tan x) = (tan^2 x + 1)/ tan x

I don't see any way to further simplify it.


1/(cosx)(sinx) or
sin^2x+cos^2x/(cosx)(sinx)

There is a sign that is 10ft on one side and 15ft on the other side (from the ground to the base of the sign), the billboard itself is 20ft.

The painter brings a 25ft ladder in length.
If the patch of ground 10ft from the base of the sign is used, at what point will the ladder touch the sign? Need two answers. 1st - length if measured from the ground and 2nd - if measured from the bottom of the sign.


What are Maximum and Minimum functions?

    Can someone please help me do this problem? That would be great! Simplify the expression: sin theta + cos theta * cot theta I'll use A for theta. Cot A = sin A / cos A Therefore: sin A + (cos A * sin A / cos A) = sin A + sin A = 2
