Ans: We use the sin 3x formula to determine the value of the sine function for an angle that is three times angle x in measurement. The formula is given by sin ... (-9A (os 3x-98 Sin 3x)+4(-3A Sin 3x + 3B Cos3x). + 4 CA Cos 3x + B Sin 3x). = [-5A ]. T-5. +12B Cos 3x + -12A-5B Sin3x= Sin 3x. Jun 4, 2022 ... This is obvious if you calculate it a few times. Since you have 3x instead of x, it is three times further away from zero than x, so to ensure ...

These are some neat identities for sin(3x), cos(3x), and tan(3x)! I'm going to quickly break down why the sin(3x) identity is true, step-by-step. Apr 30, 2019 ... KCET 2019: If f(x) = begincases ( sin 3x/e2x - 1) &; x ≠ 0 k - 2 ; x = 0 endcases is Continuous at x = 0, then k = (A) (7/2) (B) (3/2) (C) ...
