prove this identity
(sinx+cosx)/(secx+cscx)= sinxcosx if you could list out the steps it would be appreciated

The identity being asked to prove is (sinx+cosx)/(secx+cscx)= sinxcosx.
In this identity, "sin" stands for the sine function, which represents the ratio of the opposite side to the hypotenuse in a right triangle.
In this identity, "cos" stands for the cosine function, which represents the ratio of the adjacent side to the hypotenuse in a right triangle.
Proving this identity is important in mathematics because it helps to establish the relationship between different trigonometric functions and demonstrates their equivalence.
To prove this identity, we can use the fundamental trigonometric identities and algebraic manipulation. First, we can rewrite the left side of the equation using the reciprocal identities for secant and cosecant. Then, we can use the Pythagorean identities to simplify the expression further. Finally, we can use algebraic manipulation to show that the left side is equal to the right side of the equation.
