yeah. a sin is still a sin.
If tan 3a is equal to sin cos 45 plus sin 30, then the value of a = 0.4.
It is 2*sin(theta)*sin(theta) because that is how multiplication is defined!
They are both trig values, but not equal. Tan 45 is 1 and sin 45 is 0.7071
It isn't. The derivate of sin x = cos x.It isn't. The derivate of sin x = cos x.It isn't. The derivate of sin x = cos x.It isn't. The derivate of sin x = cos x.
