Nettet24. aug. 2016 · sin ( x) = 2 sin ( x 2) cos ( x 2) Therefore, we can put the above values of 1 and sin ( x) in the question. Now, we have. ∫ sin 2 ( x 2) + cos 2 ( x 2) + 2 sin ( x 2) cos ( x 2) d x And, sin 2 ( x 2) + cos 2 ( x 2) + 2 sin ( x 2) cos ( x 2) = ( sin ( x 2) + cos ( x 2)) 2 By putting the above value, we get ∫ ( sin ( x 2) + cos ( x 2)) 2 d x NettetRearrange both: sin^2x=1-cos^2x and cos^2x=cos2x+sin^2x 3. Substitute cos2x+sin^2x into sin^2x=1-cos^2x for cos^2x 4. Expand: sin^2x=1-cos2x-sin^2x 5. Add sin^2x to both sides, giving 2sin^2x=1-cos2x 6. …

NettetUse Math Input above or enter your integral calculator queries using plain English. To avoid ambiguous queries, make sure to use parentheses where necessary. Here are some examples illustrating how to ask for an integral using plain English. integrate x/ (x-1) … Compute indefinite and definite integrals, multiple integrals, numerical integration… Nettet26. jul. 2016 · Explanation: Use integration by parts, which takes the form: ∫udv = uv − ∫vdu. For ∫udv = ∫x2sin(x)dx, we let: u = x2 ⇒ du dx = 2x ⇒ du = 2xdx. dv = sin(x)dx ⇒ ∫dv = ∫sin(x)dx ⇒ v = − cos(x) Thus, substituting these into the integration by parts formula, we see that: ∫x2sin(x)dx = −x2cos(x) − ∫( − 2xcos(x))dx ... NettetAnd in this case we would want to use the Double Angle Identity. The Double Angle Identity tells us that sine squared of x is equal to 1/2 times one minus cosine of two x.
