Correct except for one thing:
I believe and i am hoping i've completed the following question is correctly... Please confirm this for me.. Many thanks in advance..
Differentate the following
y= -3 sin (2x^2)
t= (2x^2) therefore y=-3 sin t
dt/dx = 4x dy/dt= 3 cos t
dy/dx= dy/dt * dt/dx
= 3 cos t * 4x
= 3 cos (2x^2) (4x)
Is this correct...
Again mant thanks...
