For this problem I would use sec2θ = 1 + tan2θ. The problem simplifies rather nicely in a few steps. If you need more help, let us know. In the future, to get you started, look for trig functions in the problem and see if there is a trig identity that has most (or all, ...
3. Convert the non-underlined terms in the result of part two into sec or tan depending on the rule you chose to use. What identity can we use to do this? 4. What relationships between sec and tan are we taking advantage of when we ...
To do this, we can use trig definitions (such as tanx=sinxcosx) and known trig identities (such as cos2x+sin2x=1). Answer and Explanation: First, let's rewrite tanx in terms of sinx and cosx. {eq}8\cos x+8\sin x\tan x\...
