{} = integral sign for purpose of this solutioncos2x = 1 - sin2x (1)cos 2x = cos2x - sin2x (2)cos2x = 1 - (cos2x - cos 2x)cos2x...
First use the sine rule (that a/sin(A)=b/sin(B)=c/sin(C)) to find the value of B. a/sin(A)=b/sin(B) so B=arcsin(bsin(A)/a) which is approximately equal to 28.82. Since the angles of a triangle have 18...
sin-1(√2 / 4 ) = 20.7•Looking at a sin graph this is also true at 180-20.7 = 159.3•x = 159.3•
y = 4x^3 - 6x^2 + 7 dy/dx = 12x^2 -12x
From a right angled triangle with hypotenuse u and angle theta, we see the horizontal speed is (u cos theta) and the initial vertical speed is (u sin theta). As the ball moves in a symmetric parabola, it ...
