TRIGONOMETRY:
Start with sin2(θ) + cos2(θ) = 1. What would you multiply through by to get sec2(θ) = tan2(θ) + 1?

Best ResponseYou've already chosen the best response.0not just cot it should be 1/cot but how would you write tan in terms of sin cos ?

Best ResponseYou've already chosen the best response.1you just need to know the basic definitions of the trig functions, and multiply through each anser to test if it works

Best ResponseYou've already chosen the best response.1For example in using A) 1/cos^2(x) multiplying the given equation by that results in \[\frac{ \sin^2(x) }{ \cos^2(x) }+\frac{ \cos^2(x) }{ \cos^2(x) } = \frac{ 1 }{ \cos^2(x) }\]

Best ResponseYou've already chosen the best response.1right, sin^2 / cos^2 = tan^2 for the first fraction

Best ResponseYou've already chosen the best response.1and 1 / cos^2(x) = sec(x)^2 right

Best ResponseYou've already chosen the best response.0So the answer is A?

Best ResponseYou've already chosen the best response.1it appears so, because you get tan^2(x) + 1 = sec^2(x)
