find the dy/dx of s(t)= (4/3pi)sin3t+(4/5pi)cos5t
Just use the chain rule for each term
ds/dt = ds/du du/dt
u = 3t
du/dx = 3
s(u) = sin u
ds/du = cos u
So, ds/dt = (4/3π)(cos 3t)(3) + (4/5π)(-sin 5t)(5)
= 4/π cos 3t - 4/π sin 5t
Unless by 4/3π you mean 4/3 * π.
Sure! Let's find the derivative of s(t):
s(t) = (4/3π)sin(3t) + (4/5π)cos(5t)
To find the derivative of s(t), we need to apply the chain rule. The derivative of sin(3t) is cos(3t) multiplied by the derivative of 3t (which is 3), and the derivative of cos(5t) is -sin(5t) multiplied by the derivative of 5t (which is 5).
s'(t) = (4/3π)[cos(3t) * 3] + (4/5π)[-sin(5t) * 5]
Simplifying further:
s'(t) = (12/3π)cos(3t) - (20/5π)sin(5t)
s'(t) = (4/π)cos(3t) - (4/π)sin(5t)
So, the derivative dy/dx of s(t) is:
dy/dx = (4/π)cos(3t) - (4/π)sin(5t)
To find the derivative of s(t) = (4/3π)sin(3t) + (4/5π)cos(5t) with respect to t, we will differentiate each term separately using the relevant differentiation rules:
1. For the term (4/3π)sin(3t):
- The derivative of sin(3t) with respect to t is cos(3t).
- Since (4/3π) is a constant, its derivative with respect to t is 0.
- Therefore, the derivative of (4/3π)sin(3t) is (4/3π)cos(3t).
2. For the term (4/5π)cos(5t):
- The derivative of cos(5t) with respect to t is -5sin(5t).
- Since (4/5π) is a constant, its derivative with respect to t is 0.
- Therefore, the derivative of (4/5π)cos(5t) is (-4/5π)sin(5t).
Now, add the derivatives of both terms together to find the derivative of s(t):
dy/dx = (4/3π)cos(3t) + (-4/5π)sin(5t)
So, the derivative of s(t) with respect to t is (4/3π)cos(3t) + (-4/5π)sin(5t).
To find dy/dx, we need to differentiate the given function s(t) with respect to t and then divide by dt/dx. Let's work through the steps:
1. Start by differentiating the function s(t) with respect to t:
ds/dt = d/dt[(4/3π)sin(3t) + (4/5π)cos(5t)]
2. Differentiate each term separately using the chain rule:
ds/dt = (4/3π)cos(3t)(3) + (4/5π)(-sin(5t))(5)
3. Simplify each term:
ds/dt = (12/3π)cos(3t) - (20/5π)sin(5t)
4. Now, we need to find dt/dx. To do this, you'll need additional information about the relationship between t and x. If this information is not provided, it might be impossible to find dy/dx directly.
Please provide the relationship between t and x, or any additional information you may have, so we can proceed further and find dy/dx.
