2007-03-04 · integrate (tan^ 2 x) dx I believe the answer is tanx - x + c, but I can't be sure. I am completely lost on this section of calc. THANKS

x x dx. Ъ. (10 points). The odd power involves cos x, so peel off one cos x factor. (We will We then want to rewrite tan4 x as a power of tan2 x and then use a Pythagorean identity to Both x2 and sin x are easy to differentiate and integrate,.

To integrate tan2x, also written as ∫tan2x dx, and tan 2x, we use the u substitution because the integral of tanu is a standard solution in formula books. Let u=2x. Then, du/dx=2.

tan x dx = - ln |cos x| + C. = ln | (cos x) -1 | + C. = ln |sec x| + C. Therefore: tan x dx = - ln |cos x| + C = ln |sec x| + C.

The integral of tan (x) can be solved by rewriting the equation as the integral of sin (x)/cos (x) dx, and then using the integration technique called substitution. Using substitution, the value you will obtain as your answer will be. Take t = cosx. dt = - sinx dx. Substitute the values and you will get.

2. + 1. = 2t t2 + 1 och cosx = cos 2 x. 2. = cos2 x. 2 −.

To calculate an integral of the form ∫R(sinx)cosxdx, where R is a rational function, use the substitution cos2x=11+tan2x=11+t2,sin2x=tan2x1+tan2x=t21 +t2

Hence, our new integration can be writtin in terms of u and is simpler to solve. As there is no way to immediately integrate tan^2(x) using well known trigonometric integrals and derivatives, it seems like a good idea would be writing tan^2(x) as sec^2(x) - 1.

refer to the value of the trigonometric functions evaluated at an angle of x rad. If units of degrees are intended, the degree sign must be explicitly shown (e.g., sin x°, cos x°, etc.).
