New servers, hooraaaay! More bandwidth, more power.
Oops sorry, Its not squared just 2 theta
You are having trouble in sketching the graph then ?
No, the second part i.e. finding the points
Intersection method :
theta =21.47 or 158.53 see attachment. Only sin theta =(-1+sqrt(3))/2 works cos(-1-sqrt(3))/2 is less than -1
Another one: Cotx = -1.5, find the value of cosecx
For some reason, i cant work this out or more like simplify it O_ODifferentiate (product rule): x(1 + 3x^5)
15x5 + 3x5=> 18x5
Lol, I said product rule The answer is --> (1 + 3x)^4 (1 + 18x) @Alpha: Yeah but I cant seem to understand how do we end up with (1 + 18x)
