1. Change everything on the left into terms of cos and sin. Then distribute the cosx, after that try to combine anything you can, change anything you can to tanx, etc.
2. Again, change everything you can into sin and cos first, then distribute.
A few of the most important things to keep in mind are, when you are done with simplifying things and whatnot, if something is a fraction, combine the terms. In such trig identities, one of the most used basic definitions is tanx=sinx/cosx
hey you, i got this
cosX(secX+cosXcsc^2X)=csc^2x
just solve the left side
cosX[(1/cosX)+(cosx/sin^2X)]=csc^2X
then multiply ,so...
cosX(1/cosX)+cosX(cosX/sin^2X)=csc^2X
1+cot^2X=csc^2X
since 1+cot^2X one of the trig identity which equals
to csc^2X, problem solved
