How do you differentiate the following parametric equation: # x(t)=t^2+tcos2t, y(t)=tsint #?
1 Answer
Explanation:
We're asked to find the derivative of a set of parametric equations.
We differentiate each individual equation as normal:
x(t)
We can differentiate term by term, and factor out the constant,
Use the power rule:
where
Using the chain rule:
where
Simplifying:
Factor out the constant,
The derivative of
y(t)
Use the product rule:
where
The derivative of
The derivative of
