I really struggle with the C2 chapter of Trig identities and simple equations....
We haven't covered it in college yet but I watched the hegarty maths videos on the chapter..
I get it, but I keep getting the mixed exercises wrong
I don't understand the method of the questions, and for each one it is so different, this is why I am struggling with it.
Are there any resources anyone knows about I can use?
Or any tips on the methods?
A few of the Qs (0= theta, o = 0)-
Factorise 4xy - y^2 + 4x - y
Hence solve the equation 4sin0cos0 -cos^20 + 4sin0 -cos0 = o, in the interval o - 360
Find, in radian to 2 dec place, the value of x in the interval o - 2pi, for which 3sin^2x + sinx -2 = o
