Trigonometric ratios of multiple and submultiple angles formula
Trigonometric Ratios of Sub Multiple Angles : In this post we will discuss about Trigonometric Multiple and submultiple angles formula.
- (i) sin A = 2 sinA/2 cosA/2
- (ii) cos A = cos2 A/2 – sin2A/2
- (iii) cos A = 2 cos2A/2 – 1
- (iv) cos A = 1 – 2 sin2A/2
- (v) 1 + cos A = 2 cos2A/2
- (vi) 1 – cos A = 2 sin2A/2
- (vii) tan2 A/2 = (1−cosA)/(1+cosA)
