Question

Not a big fan of trigonometric equations.
Verify each trigonometric equation by substituting identities to match the right hand side of the equation to the left hand side of the equation.
-tan^2x+sec^2x=sec^2x cos^2x

Answer 1

sec^2x = 1/cos^2x

Answer 2

and tan^2x = sin^2x over cos^2x

Answer 3

sub them in and juggle around with the sin cos .. u shud can do it

Answer 4

or u could just divide the both Left hand side and right hand side by sec^2x then u will get
-tan^2x/sec^2x = cos^2x

Answer 5

then sub in 1/cos^2x for sec^2x
