This question is easily solve by factoring and knowing that $1\tan^2{x}=\sec^2x$ $$\frac{\sin x\sin x \tan^2x}{\tan x}=\frac{\sin x (1\tan^2x)}{\tan x}$$ $$\frac{\sin x \sec^2x}{\tan x}=\frac{\tan x \sec x}{\tan x}=\sec x=\boxed{\frac{1}{\cos x}}$$ In almost any mathematics excersise you should factorize whenever you can, it gives you a wider view of the2sin2 x cosx = 1 for values of x in the interval 0 ≤ x < 2π Using the identity sin2 x cos2 x = 1 we can rewrite the equation in terms of cosx Instead of sin2 x we can write 1− cos2 x Then 2sin2 x cosx = 1 2(1− cos2 x)cosx = 1 2−2cos2 x cosx = 1 This can be rearranged to 0 = 2cos2 x −cosx− 1 You can check some important questions on trigonometry and trigonometry all formula from below 1 Find cos X and tan X if sin X = 2/3 2 In a given triangle LMN, with a right angle at M, LN MN = 30 cm and LM = 8 cm Calculate the values of sin L, cos L, and tan L 3
