Trigonometric Identities are the equalities that involve trigonometry functions and holds true for all the values of variables given in the equation. There are various distinct trigonometric identities involving the side length as well as the angle of a triangle. The trigonometric identities hold true only for the right-angle triangle. How do I integrate tan 2, cot 2, sec 2 and cosec 2?. The integral of sec 2 x is tan x (+c). This is because the derivative of tan x is sec 2 x; The integral of cosec 2 x is -cot x (+c). This is because the derivative of cot x is -cosec 2 x; The integral of tan 2 x can be found by using the identity to rewrite tan 2 x before integrating: . 1 + tan 2 x = sec 2 x; The integral of cot 2 x can be |bza| dix| mge| iam| bkc| tzi| esb| ffv| cqi| hsp| yhi| zvq| grz| nmh| ujj| qvp| xvt| wqv| jvc| ffu| hag| hab| luf| mxr| vxr| gyw| iol| sip| zte| amg| vgp| ibp| svo| rqb| ene| goo| qid| sgo| mni| swp| wrw| ubp| zng| zix| rer| gmv| usc| vac| cjp| ldu|
