Cos2x 32

Now we know that integration of x^n is x^(n1)/n1Therefore the integration of x^(1/2) is x^(1/2)/1/2 or it can be simply written as 2x^1/2Hereby I conclude that 1/x^( 1/2) is integrable Hope it helps 😀😀.

To find the value of sin of 2pi, let us first recall the sine function for different standard angles from the trigonometric table sin 0 = 0, sin π/6 = 1/2, sin π/4 = √2/2, sin π/3 = √3/2, and sin π/2 = 1 This table does not contain the value of sin 2pi Various methods will be used here to find that sin of 2pi is 0 A few examples will also be given to illustrate how this works. 2 √1 √ 3 2 1 cos 1 √ 3 2 √1 1 2 0 tan 0 √1 3 1 √ 3 ∞ 3 Some simple trigonometric equations Example Suppose we wish to solve the equation sinx = 05 and we look for all solutions lying in the interval 0 ≤ x ≤ 360 This means we are looking for all the angles, x, in this interval which have a sine of 05 We begin by sketching a graph of the function sinx over the given. Lets say I have to solve cos2x= √ 3/2 So the first thing I have to do is to find √ 3/2 on the unit circle But the problem is there is two.

Sin A = ±√(1 − (3/5) 2) sin A = ±√(16/25) sin A = ± 4/5 Since A is in quadrant I, sin⁡ A is positive Thus, sin A = 4/5 From sin2x formula, sin2x = 2 sin x cos x From this, sin2A = 2 sin A cos A = 2 (4/5) (3/5) = 24/25 Answer The value of sin⁡2A = 24/25 Example 2 If sin A = 2/3 where A is in quadrant I, then find the value of sin2A Solution We have sin 2 A cos 2 A = 1. We know that cos2x = cos 2 x sin 2 x and sin 60° = √3/2, cos 60° = 1/2 Since 2x = 1°, x = 60° Therefore, we have cos 1° = cos 2 60° sin 2 60° = (1/2) 2 (√3/2) 2 = 1/4 3/4 = 1/2 Important Notes on Cos 2x cos2x = cos 2 x sin 2 x;.  Example 42 Evaluate ∫1 (sin⁡〖2𝑥 cos⁡2𝑥 〗 𝑑𝑥)/(√(9 −cos^4⁡(2𝑥) ) ) 𝑑𝑥 ∫1 (sin⁡〖2𝑥 cos⁡2𝑥 〗 𝑑𝑥)/(√(9 − cos^4⁡2𝑥 ) ) 𝑑𝑥 Let cos^2⁡2𝑥=𝑡 Differentiating both sides wrt𝑥 –22 cos⁡2𝑥 sin⁡2𝑥=𝑑𝑡/𝑑𝑥 𝑑𝑥=𝑑𝑡/(–4 cos⁡2𝑥 sin⁡2𝑥 ) Hence, our equation becomes ∫1 (sin.
