What number is one fourth of 360?

MTH 132 Lecture 9 Trigonometric Derivatives Sine and Cosine addition ● sin(a+b) = sin(a)cos(b)+cos(a)sin(b) ● cos(a+b) = cos(a)cos(b)sin(a)sin(b) Derivative of Sine ● sin(x)’ = cos(x) Sine Proof ● [ sin(x+h) sin(x) ] / h ● [ Sin(x)cos(h) + cos(x)sin(h) sin(x) ] / h ● Cos(x) * sin(h)/h sin(x) * (cos(h) 1)/h ○ [cos(h) 1]/h...
