Splet15. sep. 2015 · We know that sin2x + cos2x = 1 hence cos2x = 1 −sin2x. thus. 5sin2x + 3(1 −sin2x) = 4 ⇒ 5sin2x +3 −3sin2x = 4 ⇒ 2sin2x = 1 ⇒ sinx = ± √2 2 ⇒ x = π 4,x = 3π 4,x = 5π 4,x = 7π 4.

(2) SpletThis means ∫π 0 sin(x)dx= (−cos(π))−(−cos(0)) =2 ∫ 0 π sin ( x) d x = ( − c o s ( π)) − ( − c o s ( 0)) = 2. Sometimes an approximation to a definite integral is desired. A common way to do so is to place thin rectangles under the curve and add the signed areas together. Wolfram Alpha can solve a broad range of integrals.. internet banking icon
