Note that tan (x+π2)=sin(x+π2)cos(x+π2).
For the numerator, use sin(A+B)=sin(A)cos(B)+cos(A)sin(B):
sin(x+π2)=sin(x)cos(π2)+cos(x)sin(π2)
=sin(x)⋅0+cos(x)⋅1
=cos(x)
In the denominator, use cos(A+B)=cos(A)cos(B)−sin(A)sin(B):
cos(x+π2)=cos(x)cos(π2)−sin(x)
Thus, we see that
tan(x+π2)=sin(x+π2)cos(x+π2)=cos(x)−sin(x)=−cot(x)
