Basic Rules of Differentiation

Solve [d/dx] (92828237 + √{13})
• [d/dx] 92828237 + [d/dx] √{13} = 0 + 0 =
0
Simplify [d/dx] 3x2
[d/dx] 3x2 = 3 [d/dx] x2
Simplify [d/dx] (5x3 + 12)
• [d/dx] (5x3 + 12) = [d/dx] 5x3 + [d/dx] 12
• = 5 [d/dx] x3 + 0
5 [d/dx] x3
Simplify [d/dx] (5cos(3x) + 4x)
[d/dx] (5cos(3x) + 4x) = 5 [d/dx] cos(3x) + 4 [d/dx] x
Simplify [d/dx] ex + 1
[d/dx] ex + 1 = [d/dx] ex e1 = e1 [d/dx] ex
Simplify [d/dx] ln(5)
[d/dx] ln(5) = 0
Simplify [d/dx] (x + 3)2
• [d/dx] (x + 3)2 = [d/dx] (x2 + 6x + 9)
• = [d/dx] x2 + [d/dx] 6x + [d/dx] 9
= [d/dx] x2 + 6 [d/dx] x
Simplify [d/dx] ([(x2 + 5x + 6)/(x + 2)])
• [d/dx] ([(x2 + 5x + 6)/(x + 2)]) = [d/dx] ([((x + 3)(x + 2))/(x + 2)])
• = [d/dx] (x + 3) = [d/dx] x
x
Simplify [d/dx] (e5 + e5x + sin(π))
• [d/dx] (e5 + e5x + sin(π)) = [d/dx] e5 + [d/dx] e5x + [d/dx] sin(π)
• = [d/dx] e5x
[d/dx] e5x
Simplify [d/dx] e7 sin(5x2)
• [d/dx] e7 sin(5x2) = e7 [d/dx] sin(5x2)
e7 [d/dx] sin(5x2)
