Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. Hi how would you solve (1-tanx)(2 sinx+1) so that you can get rid of the tan X? Thanks

That is not an equation so it can't be solved.

Please rewrite it with an '=' sign.

Sorry, (1-tanx)(2 sinx+1)=0

I don't know what you mean by get rid. But when you have , a or b or both a and b are 0.

If the question is asking you to solve, im guessing you can make each bracket equal to 0. The same way you'd solve (x-3)(x+2), then use the cast diagram or whatever method you use to find all the values of x.

If you want to "get rid" of the tan x, you can apply the rule, (sin theta)/(cos theta) = (tan theta). So you can replace tanx with sinx/cosx.
