Answer:
Step-by-step explanation:
Use the pythagorean theorem
plug in and solve
if you need to solve for the sides
3x = 3(4.7434) = 14.2302
Answer: plug in the top equation for what y equals into the bottom equation and then that should be a easy way to solve this
Step-by-step explanation:
Applying implicit differentiation, it is found that dy/dt when y=π/4 is of:
a-) -√2 / 2.
<h3>What is implicit differentiation?</h3>
Implicit differentiation is when we find the derivative of a function relative to a variable that is not in the definition of the function.
In this problem, the function is:
xcos(y) = 2.
The derivative is relative to t, applying the product rule, as follows:
Since dx/dt=−2, we have that:
When y = π/4, x is given by:
xcos(y) = 2.
Hence:
Since cot(pi/4) = 1, we have that:
Which means that option a is correct.
