Web5 mei 2024 · 6 y 2 d y d x = 2 x + 2 cos ( 2 y) d y d x This works because when we need to differentiate a function of y w.r.t x, we can use the Chain Rule. This can be seen more explicitly by letting, u = 2 y 3 and v = sin ( 2 y). Now the equation becomes: u = x 2 + v and we can differentiate u and v w.r.t x via the Chain Rule: WebThe law of cosines allows us to find angle (or side length) measurements for triangles other than right triangles.
