WebQ: Convert the angle 330° in degrees to radians. Express your answer as a multiple of π. A: We know that π radian=180° So, 1°= π/180 radian Q: use the half angle formula to find the exact value, not a decimal approximation. of cos (pi/8) A: Half angle formula of cos, cos2A=2cos2A-1 2cos2A=cos2A+1cosA=cos2A+12 Q: How many radians is 45°? 4. WebAnswer: Given below is the formula for converting radians into degree is, Degrees = Radians∗180 / π. Degrees = 2.56∗180 / π. Degrees = 3,225.6 / π. Degrees = 146.75. …
