dy/dx = 2xcos(x2+2)
step 1 ; expand the brackets5x - 15 = 4y - 3xystep 2 ; group together x values on one side5x + 3xy = 4y + 15step 3 ; single out xx (5+3y) = 4y +15step 4 ; make x the subjectx = (4y + 15) / (5+3y)
Using Pythagoras' theorem: a2 = b2 + c2You can use the length of the other two sides to calculate a.
