Question

determine all the solutions of the following equations:

1) (cos^2x)(senx) = cos x

Answer 1

do you mean to prove? and im assuming senx is secx

LEFT HAND SIDE:
\(\Large (\cos^2 x)(sec x) = (\cos^2 x)(\frac{1}{\cos x}) = \cos x = RHS\)

rhs -> right hand side

Answer 2

no, it's not to prove it ... and the equation is with sen not sec

Answer 3

what trig function is sen o.O
