The computation can be done simply as follows tan2xsin3x=sin2xsin3xcos2x=2sinxcosx[sinx(2cos2x+1)]cos2x=2cosx(2cos2x+1)cos2x→2⋅1(2 ... May 13, 2015 ... The problem is: lim x->0 of (tan7x)/(sin3x) I know that lim x->0 (sinx)/x = 1, but I don't really know how to apply that here. Sin3x is a triple angle identity in trigonometry. The expansion of sin3x formula can be derived using the angle addition identity of the sine function. 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 ...
