Crazy how easy this is now. This was my biggest struggle in calc one

I would emphasize that x is not always 5 but the ladder is always 13. That’s why we can substitute in for the ladder before differentiation but not the x.

“Real world problem”. So many times my ladder was crashing down at a constant rate and I needed to know this answer 😁

can you do more complex rate problems I really struggle with these

Why did you add a 2 on the y and x when finding the derivative of x and y?

just take the 0 on these

why did u write dy/dx in 2nd step when u already did do dy/dx of x^2

Can you do this except you have to find the rate of change of an angle(theta)?

Crazy how simple this problem seems now, just last night I thought it was impossible, now 4 minutes before my quiz: seems doable

This was the hardest part of calc one for me so far, missed both questions on the test

fishywashy :
could you also Differentiate with respect to X to get 2x + 2y(dy/dx)=0 then isolate dy/dx, then multiply it by dx/dt to get dy/dt (via chain rule)?

Can you do the trig version of these problems with dtheta
