(a+b)2=a2+2ab+b2 (a−b)2=a2−2ab+b2 (a−b)(a+b)=a2−b2 Answer and Explanation:1 We have to simplify the given trigonometric expression(1+secx)2−tan2x. To do so, apply the identity... Learn more about this topic: ...
Two other Pythagorean Trig Identities that can be found form this one are the following. 1+tan2(x)=sec2(x) 1+cot2(x)=csc2(x). We know to use these identities when verifying an identity if our trigonometric functions are squared. Answer and Explanation: We are asked to prove: ...
Integrals involving tan(x), sec(x), cot(x), csc(x) Rule 1. If the power of sec or csc is even and positive, save a sec or csc squared factor and convert the remaining factors to tangents. Rule2. If the power of the tan or co...
