How can you tell if a triangle is sine cosine or tangent?

Evaluate the integral. (sec2(t) i t(t2 1)8 j t7 ln(t) k) dt

If t8 = 4 and t12 = −2, find the first three terms of the arithmetic sequence.

A)a square brown tarp has a square green patch green in the corner the side length of the tarp is (x + 8) and the side length of the patch is x what is the area of the brown part of the tarpb)a square red placemat has a gold square in the corner the side length of the gold square is (x - 2) inches with the width of the red region is 4 in what is the area of the red part of the placemat
