I checked the solutions in Pearson textbook. They are correct.Solution very nicely set out and handwriting really neat.
But not sure if your answers fully correct.
Damn this is so much cleanerAn alternate method:
Hi,
For (a) and (b), you can either use t-formula or auxiliary angles, but not sure if they are in 2U. For (c), try converting sec and tan to cos and sine and then simplify, and for (d) simply use your double angle formula's and simplifyThanks everyone,
Do guys know how to do these ones as well? They're from the same textbook, Fitzpatrick, Exercise 12.2 Question 7

Pretty sure that T-formula and auxiliary angles are in 3u but I was wondering if there was a way to solve this question using 2u contentFor (a) and (b), you can either use t-formula or auxiliary angles, but not sure if they are in 2U. For (c), try converting sec and tan to cos and sine and then simplify, and for (d) simply use your double angle formula's and simplify
I only have worked solutions for every odd question, here are the ones from the textbook for odd questions:There were some other ones I didn't understand from this chapter either, could you please help me out with these ones too?

Thanks again in advance
for (a), divide both sides by cosx, then square both sides, use the identity tan^2(x)+1=sec^2(x) to get the equation in terms of tan^2(x), then solve as usual. This method can be applied to all of 7. (note this may give extra solutions plug back in to verify, and also it may miss some solutions, nothing you can do).Thanks everyone,
