Which is the value of sin2x cos2x?
To find the value of sin2x × Cos 2x, the trigonometric double angle formulas are used. For the derivation, the values of sin 2x and cos 2x are used. So, Sin 2x Cos 2x = 2 Cos x (2 Sin x Cos2 x − Sin x)
What is the maximum value of sin 2x?
The maximum and minimum values for sin(x) is 1 and -1. The value of sin^2(x) at these points is 1. Sticking the maximum value of sin(x) in the equation you get the maximum of 1 + 4*1 -1 = 4.
What is the maximum value of cos 2?

|---|---|---|
| cos θ, cos 4θ , cos 7θ … cos nθ | -1 | +1 |
| sin2 θ , sin2 4θ , sin2 9θ …sin2 nθ | 0 | +1 |
| cos2 θ , cos2 3θ , cos2 8θ … cos2 nθ | ||
| Sin θ Cos θ | -1/2 | +1/2 |
What is the minimum value of cos 2x?
Minimum value is 4-√10 and maximum value is 4+√10. Explanation follows on the hand note below.
What is the integration of cos 2x sin 2x?
Solved Examples Therefore the integral of sin 2x cos 2x is ∫ (Sin 2x Cos 2x) = (Sin 2x) 2 / 4 + C.
How do you convert sin 2x to cos2x?
They are three double angle formula for cos2x which are; cos2x = cos2x−sin2x. cos2x = 2cos2x−1.
What is the maximum value of (cos x^2 – (sin x)^2)?
Since (cos x)^2 – (sin x)^2 = cos 2x and since the maximum value of cos 2x is 1, then the maximum value of (cos x)^2 – (sin x)^2 is also 1. The maximum value for the cosine function for any value of x is 1. So, the maximum value of cos²x-sin²x is 1.
What is the maximum value of the product of Sine and cosine?
Answer: =1. {For the maximum value, The second term, [3* (sin^2x)* (cos^2x)] must be minimum, which is only when x is 0. Therefore the product of sine and cosine term will be equal to 0. } Hence, the maximum value is 1.
What is the maximum and minimum value of tan x?
The maximum is obtained when tan x = 2, with x in Q1. And this is = √5. Of course, the minimum is −√5.
