True Start with the well known pythagorean identity sin^2x cos^2x = 1 This is readily derived directly from the definition of the basic trigonometric functions sin and cos and Pythagoras's Theorem Divide both side by cos^2x and we get sin^2x/cos^2x cos^2x/cos^2x = 1/cos^2x tan^2x 1 = sec^2x tan^2x = sec^2x 1 Confirming that the result is an identitySometimes, it pays to be able to associate certain expressions in mathematics with other wellknown ones That's a trick which can help us find a suitable "formula" for the above expression Take some time and try to recall which mathematical exprFor all values of x tan^2xsec^2x=1 true or false?
Solution for ((2tan^2x)/sec^2x) 1 solve showing work Social Science AnthropologyYes, sec 2 x−1=tan 2 x is an identity sec 2 −1=tan 2 x Let us derive the equation We know the identity sin 2 (x)cos 2 (x)=1 ——(i) Dividing throughout the equation by cos 2 (x) We get sin 2 (x)/cos 2 (x) cos 2 (x)/cos 2 (x) = 1/cos 2 (x) We know that sin 2 (x)/cos 2 (x)= tan 2 (x), and cos 2 (x)/cos 2 (x) = 1 So the equation (i) after substituting becomes The cos2(2x) term is another trigonometric integral with an even power, requiring the powerreducing formula again The cos3(2x) term is a cosine function with an odd power, requiring a substitution as done before We integrate each in turn below ∫cos2(2x) dx = ∫ 1 cos(4x) 2 dx = 1 2 (x 1 4sin(4x)) C
