2018-03-08 · to sines using #cos^2x=1-sin^2x# and then use the substitution #u=sinx# Case 3: If both #n# and #m# are odd, we can use either method used in Case 1 & 2. Case 4: If both #n# and #m# are even we will need to use double angle and/or half angle formulas to reduce the integral into something we can integrated easier. 2018-05-29 · Ex 7.3, 21 sin﷮−1﷯﷮ cos﷮𝑥﷯﷯﷯ ﷮﷮ sin﷮−1﷯﷮ cos﷮𝑥﷯﷯﷯﷯𝑑𝑥 = ﷮﷮ sin﷮−1﷯﷮ sin﷮ 𝜋﷮2﷯ −𝑥﷯﷯﷯𝑑𝑥﷯﷯ = ﷮﷮ 𝜋﷮2﷯ −𝑥﷯﷯𝑑𝑥 = ﷮﷮ 𝜋﷮2﷯﷯ 𝑑𝑥− ﷮﷮𝑥﷯𝑑𝑥 = 𝜋﷮2﷯ ﷮﷮1﷯ 𝑑𝑥− ﷮﷮𝑥﷯𝑑𝑥 = 𝝅﷮𝟐﷯ 𝒙 − 𝒙﷮𝟐﷯﷮𝟐﷯ +𝑪 the integral of sinx.cos^2x is: you have to suppose that u=cosx →du/dx= -sinx →dx=du/-sinx → then we subtitute the cosx squared by u and we write dx as du/sinx so sinx cancels with the sinx which is already there then all we have is the integratio Misc 26 - Chapter 7 Class 12 Integrals Last updated at Dec. 23, 2019 by Teachoo Integration Full Chapter Explained - Integration Class 12 - Everything you need Solve the integral = - ln |u| + C substitute back u=cos x = - ln |cos x| + C Q.E.D. 2.

now substituting these in the above integral. since where c is the integration constant.. therefore the above integral becomes What is the integral of sin(x)? Please allow me to answer this question slightly differently - by following in the footsteps of Isaac Barrow (1630–1677) (the teacher of Isaac Newton), Isaac Newton (1642–1726), Gottfried Leibniz (1646–1716), Bernhard Riemann (1826–1866) and, not to forget, Euclid, Archimedes and numerous anonymous Greek like-minded individuals of the past.
