The value of cos 15 degrees is 0.9659258. Cos 15 degrees in radians is written as cos (15° × π/180°), ie, cos (π/12) or cos (0.261799). sin(A B) = sinAcosB cosAsinB , cos(A B) = cosAcosB + sinAsinB , find the values of sin15 and cos15. Oct 13, 2021 ... We know cosC + cosD = 2cos(C+D)/2.cos(C–D)/2 , Therefore, · (Cos105°+Cos 15°) · =2cos(105+15)°/2*cos(105–15)°/2 · = 2cos60°.cos45° · = 2*1/2*(1/ ...
