Determine whether the given relation is an implicit solution to the given differential equation. Assume that the relationship does define y implicitly as a function x and use implicit differentiation. x2−sin(x+y)=1,dydx=2xsec(x+y)−1

168

step-by-step explanation:

i am pretty sure that the answer is 168

uhhh idk u yolo?

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

m∠a is 90°

m∠b is 40°
