integral of sin 2 x Now using the simplified value for sin 2 x the integral converts to sin 2 x dx 1 cos 2x 2 dx 1 dx 1 2 cos 2x dx sin 2 x x 2 sin 2x 4 C Since the integral of cos ax sin ax a Note Here cos 2x dx value can be computed using integration by substitution where C is the constant of
For sin 2 X we will use the cos double angle formula cos 2X 1 2sin 2 X The above formula can be rearranged to make sin2 X the subject sin 2 X 1 2 1 cos 2X You can now rewrite the integration sin 2 X dX 1 2 1 cos 2X dX Because 1 2 is a constant we can remove it from the integration to make the calculation The sin 2x formula is the double angle identity used for sine function in trigonometry Trigonometry is a branch of mathematics where we study the relationship between the angles and sides of a right angled triangle There are two basic formulas for sin 2x sin 2x 2 sin x cos x in terms of sin and cos sin 2x 2tan x 1 tan 2 x in

int sin 2 x dx Method 1 Integration of Cos 2x Using Double Angle Formula To find the integral of cos 2 x we use the double angle formula of cos One of the cos 2x formulas is cos 2x 2 cos 2 x 1 By adding 1 on both sides we get 1 cos 2x 2 cos 2 x By dividing by both sides by 2 we get cos 2 x 1 cos 2x 2
In this case we want an identity which will relate sin 2 x to a function we can integrate A little thought tells us that the cosine double angle formula helps This is cos 2x 1 2sin 2 x Rearrange to make sin 2 x the subject of the formula sin 2 x 1 cos 2x 2 No the integral of sin x is NOT cos x in fact the integration of sin x is cos x C How to Find Integral of Sin x We know that d dx cos x sin x Multiply both sides by 1 we get d dx cos x sin x Therefore the integral of sin x as it is the anti derivative of sin x is cos x C What is the Integral of Sin x From 0 to 2

What Are Sin Squared x Formulas Using one of the trigonometric identities we have sin 2 x cos 2 x 1 Subtracting cos 2 x from both sides we get sin 2 x 1 cos 2 x Thus one of the sin squared x formulas is The integral of sin 3x can be calculated using the formula for the integral of sin ax which is given by sin ax dx 1 a cos ax C Mathematically the integral of sin 3x is written as sin 3x dx 1 3 cos 3x C where C is the constant of integration dx denotes that the integration of sin 3x is with respect to x is the symbol for integration
