Question

sin(-x)/cos(x)

Solve this problem.

Answer 1

sin(-x)/cos(x) = -sin(x)/cos(x) = -tan(x)

Answer 2

Answer 3

To solve any problem like this, it can be helpful to write the trig function in terms of the sides of a right triangle: hypotenuse (H)

opposite (O)

adjacent (A)

sin(x) = O/H

cos(x) = A/H

therefore sin/cos = (O/H) / (A/H) = O/A = tan
