can you please show the step by step process on how to get the answer? thanks!
41) ∫ (xdx) / (7x^2 + 3)^5
42) ∫ (sint) / (3 + cos t)^3 dthow do i solve this? i have no idea where to start...can you have a step by step process/analysis on how to figure out the answer? thanks!
1) (dy/dx) = (1) / ( 2√x ) + 10 , y(1) = -1
2) (d^(2)r / dt^2) = ( 4 / t^3 ) ; (dr/dt) | t=1 = -5, r(1)=5
... i have no idea where to start.
what are the steps needed to figure out the answer...can someone please solve this for me! t
thank you so much.
