We will learn how to express the multiple angle of sin 2A in terms of tan A. Trigonometric function of sin 2A in terms of tan A is ... Substituting this in the above formula, sin2A = 2 sin A √(1 - sin2A). This formula is in the terms of sin or sine function only. May 7, 2020 ... Step-by-step explanation: 2 sin square( 45°-A) (therefore; by trigonometry ratios sin45°=1) =2sin2(1-A) =2sin(1-A) =1+sin2A hence proved. Use the definition of sin s i n to find the value of sin(a) sin ( a ) . In this case, sin(a)=1213 sin ( a ) = 12 13 . sin2A/cos2A+cos2A/sin2A = 1/(sin2A cos2A) - 2 ...
