To achieve this end, we can start with either of the sides and simplify it. Answer and Explanation: The given equation that needs to be shown to be an identity is: (1−tanx)2+(1+tanx)2=2sec2x The left-hand side of the equation may b...
Verifying Trigonometric Equation: To confirm if this equation is an identity, we need replace the cosecant function {eq}(\csc x) {/eq} by its equivalent reciprocal function. From there, simplify and use the other identities, such as the Pythagorean Identities, to take the...
