Non negative just includes 0, your b will still be negative.

Re: (Less than) 21 Trig Questions from Amrita
Hmm, they are integers. And because b is +ve, they are negative too. We need to find c1,c2 such that the bracketed expression form the lowest absolute value. So, c1,c2 = -1,-1. But it is still not working?

I'll have a try:
If
tan(x) = 1
Then, what is the value of x?

Re: (Less than) 21 Trig Questions from Amrita
The tan of -315, -135, 45, 225 Degrees is 1 too
So,
tan(x) = 1
⇒ x ∈ {...., -315 Degree, -135 Degree, 45 Degree, 225 Degree, ...}
Represent that set through set builder notation, Can you?

2.If a,b are two values of x (0 <= a,b <= 2 π ) which satisfy the equation 6 cos x + 8 sin x = 9, Find sin (a+b)
Any way to do this one without having to plot the curve?
