1
Q
What are the steps of the chain rule
A
•Differentiate the bracket, ignoring what is inside
•Multiply by the differential of inside the bracket
2
Q
If we need to find the equation of a tangent using chain rule
A
- sub in point to get y
- differentiate with chain rule to get gradient
3
Q
What are the two tricky trig terms to differentiate between
A
f(x) = sinx2 = sin(x2)
f(x) = sin2x = (sinx)2
4
Q
What is the differential of sinx and cos x
A
f(x) = sinx - cosx
f(x) = cosx = -sinx
5
Q
If there is more than one term on top of a single term
A
Separate into multiple fractions
6
Q
To calculate angle that isn’t an exact value
A
Check where it would lie on the cast diagram
How far away is it from 180 or 360
Find that number in exact value triangle
7
Q
What is the integral of cosx and sinx
A
Cosx = sinx
Sinx = -cosx
