Oct 28, 2023 ... sin2x = 2sinxcosx so if you multiply sin2x by 1/2 then you do the same to the other side and so 1/2 times 2sinxcosx is sinxcosx. Therefore 1 ... = ex, y(1) = 2. What is the value of y(2)?. A. e2 + 2. B. e. 2. C. e2+2. 2. D. e ... sin(2x) + c4x cos(2x) + c5x sin(2x)]. B. c1 cos x + c2 sin x + e−3x[c3 ... Dec 16, 2024 ... ... 1/2 ∫1·t^2/2 dt) = t^2 〖tan〗^(−1) t−∫1·t^2/(1 + t^2 ) dt Solving I_1 I_1 = ∫1·t^2/(1 + t^2 ) dt Adding and ... Mar 23, 2013 ... But the area of △ABC is 12sin2φ. Not elegant, to be sure, but quick. Share. First, we use the trig identities: cos2x=cos^2x-sin^2x, cos^2x+sin^2x=1 and sin2x=2sinxcosx to transform the integral to ∫(cos2x)/(1+sin2x)dx. 1 : direction change at 1, 2. 1 : interval with reason. v t t ...
