1. d/dx [ e^x ] = e^x
2. d/dx [ e^(ax+b) ] = a e^(ax+b)
3. d/dx [ ln (ax + b) ] 1/(ax+b) . a

1. d/dx [ sin x ] = cos x
2. d/dx [ cos x ] = -sin x
3. d/dx [ tan x ] = sec² x
4. d/dx [ sin (ax+b) ] = a cos (ax+b)
5. d/dx [ cos (ax+b) ] = -a sin (ax+b)
6. d/dx [ tan (ax+b) ] = a sec² (ax+b)
7. d/dx [ sinⁿx ] = n sin^(n-1) x . cos x
8. d/dx [ cosⁿx ] = n cos^(n-1) x . -sin x
9. d/dx [ tanⁿx ] = n tan^(n-1) x . sec² x

dy/dx (axⁿ) = nax^(n-1)
dy/dx [ 2x² + 5x + 7 ]
= 4x + 5
dy/dx [ x/3 - 3/x - 4/x² ]
= 1/3 + 2/x² + 8/x^3Chain Ruledy/dx [ (x²+1)^7 ]
= 7(x²+1)^6 . 2xProduct Rule dy/dx [ (x+7)^10 . (x²+2)^7 ]
= (x+7)^10.7(x²+2)^6.2x + (x²+2)^7.10(x+7)^9.1
Write 1st . dy/dx 2nd + Write 2nd . dy/dx 1stQuotient Ruledy/dx [ (2x+5) / (3x-4) ]
= [ (3x-4).2 - (2x+5).3 ] / (3x-4)²
Write btm . dy/dx TOP - write top . dy/dx btm ; then square btm
