sec and tan relationship

(1) 1 + tan2 u = sec2 u. (2) (tan u) = sec2 u. (3) (sec u) = sec u tan u. These set of identities are particularly useful when integrating powers of tan and sec, as. tan2(t) + 1 = sec2(t) You can see the Pythagorean-Thereom relationship clearly if you consider the unit circle, where the angle is t, the "opposite" side is sin(t). They can be easily replaced with derivations of the more common three: sin, cos and tan. Secant can be derived as the reciprocal of cosine: sec. x. = 1. cos.
