Solve for x, 5sin(x) - 3cos(x) = 2 , in the interval 0<x<2pi

5sin(x)-3cos(x)=2 Express in the form Rsin(x-@) = Rsin(x)cos@ - Rcos(x)sin@ Rcos@ =5 Rsin@ = 3 tan@ = 3/5 @=tan -1 (3/5)= 0.540 R = sqrt(5 2 +3 2 )= sqrt(34) sqrt(34)sin(x-0.540) = 2 sin(x - 0.540) = 0.343 L...

Use implicit differentiation to find dy/dx of: 2(x^2)y + 2x + 4y - cos((pi)y) = 17

Tackle this problem one part at a time: First differentiate 2x 2 y using the product rule, showing dy/dx(2x 2 y) = 4xy + 2x 2 (dy/dx). After this, the remainder of the question is easier, as there are no mor...
