Homework Help: TRIGONOMETRY

Posted by Kate on Saturday, May 18, 2013 at 10:31am.

Can someone please show me step by step solutions? I'd appreciate if you did so I know how you get the answer. Thank you so much!

Solve each equation, giving a general formula for all of the solutions:
a)2sin^2 x-5sinx-3=0
b)(cosx-(sqrt2/2))(secx-1)=0

Would the general formula be tan x=sin x/cos x?
