Question

Differentitae the function f(x)=sinx+cosx/sinx-cosx with respect to x

Answer 1

Answer:

Step-by-step explanation:

First divide cosx in numerator and denominator. Then substitute 1 to tan π/4 in numerator and write the tanx = tan(π/4).tanx [as tan (π/4) = 1]. Then you get an expression of tan(A+B). Finally you get f(x) = tan(π/4 + x). Now differntiate if w.r.t. x.
