Practice problem
What is sin(5π12)\sin(\frac{5\pi}{12})sin(125π)?
Hint: sin(A+B)=sin(A)cos(B)+cos(A)sin(B)\sin(A + B) = \sin(A)\cos(B) + \cos(A)\sin(B)sin(A+B)=sin(A)cos(B)+cos(A)sin(B)
1+22\frac{1 + \sqrt{2}}{2}21+2
23\frac{\sqrt{2}}{3}32
2+34\frac{\sqrt{2} + \sqrt{3}}{4}42+3
2+64\frac{\sqrt{2} + \sqrt{6}}{4}42+6
Type a concept, like “slope” or “photosynthesis”.
