Because g(x) = −2x has negtive slope so that means it goes downward also there is no y-intercept in g(x) = −2x but the only graph that has y-intercept in given graph goes upwawrd so that can't be answer. g(x) = −2, x < −2.

We will use the trigonometry identity cos 2 x + sin 2 x = 1 to prove that cos2x = 1 - 2sin 2 x. We have, cos2x = cos 2 x - sin 2 x = (1 - sin 2 x) - sin 2 x [Because cos 2 x + sin 2 x = 1 ⇒ cos 2 x = 1 - sin 2 x] = 1 - sin ...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 ... Let us equate, X and Y, i.e. X = Y. So, the above formula for cos 2X, becomes. cos 2X = cos(X + X) = cos X cos X– sin X sin X. cos 2X = cos2 X–sin2 X. Hence, the first cos 2X formula follows, as. cos 2X = cos2 X–sin2 X. And for this reason, we know this formula as double the angle formula, because we are doubling the angle.Let us equate, X and Y, i.e. X = Y.

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. We use this to find ∫ cos 2 x dx. Then we get. ∫ cos 2 x dx = ∫ (1 + cos 2x) / 2 dx.Solve your math problems using our free math solver with step-by-step solutions.
