3. Find the common roots of the equations 2sin^2x+sin^22x=2 and sin2x+cos2x=tanx
2sin(x)cos(x)(3 - 4sin2(x)) = 0. If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0. sin(x) = 0. cos(x) = 0. 3 - 4sin2(x) = 0. Set sin(x) equal to 0 and solve for x. Tap for more steps. x = 2ฯn, ฯ + 2ฯn, for any integer n. Set cos(x) equal to 0 and solve for x.

To derive the sin 2 x formula, we will use the trigonometric identities sin 2 x + cos 2 x = 1 and the double angle formula of cosine function given by cos 2x = 1 - 2 sin 2 x. Using these identities, we can express the formulas of sin 2 x in terms of cos x and cos 2x.. sin 2 x = 1 - cos 2 x; sin 2 x = (1 - cos 2x)/2; Let us derive the formulas stepwise below: Sin^2x Formula in Terms of Cosx

tan^2x = sin^2x / cos^2x โ tan 2 x = sin 2 x/cos 2 x; tan^2x = 1/cot^2x โ tan 2 x = 1/cot 2 x; What is the Difference Between tan2x and tan^2x? Tan2x is a double angle trigonometric formula which gives the value of the tangent function for the compound angle 2x. On the other hand, tan^2x is the whole square of the trigonometric function tanx.

Now, that we have derived cos2x = cos 2 x - sin 2 x, we will derive cos2x in terms of tan x. We will use a few trigonometric identities and trigonometric formulas such as cos2x = cos 2 x - sin 2 x, cos 2 x + sin 2 x = 1, and tan x = sin x/ cos x. We have, cos2x = cos 2 x - sin 2 x = (cos 2 x - sin 2 x)/1 = (cos 2 x - sin 2 x)/( cos 2 x + sin 2 x) [Because cos 2 x + sin 2 x = 1]. Divide the.
