Find the first partial derivative with respect to t
∂s∂v=t1
Simplify
v=ts
Find the first partial derivative by treating the variable t as a constant and differentiating with respect to s
∂s∂v=∂s∂(ts)
Use differentiation rule ∂x∂(g(x)f(x))=(g(x))2∂x∂(f(x))×g(x)−f(x)×∂x∂(g(x))
∂s∂v=t2∂s∂(s)t−s×∂s∂(t)
Use ∂x∂xn=nxn−1 to find derivative
∂s∂v=t21×t−s×∂s∂(t)
Use ∂x∂(c)=0 to find derivative
∂s∂v=t21×t−s×0
Any expression multiplied by 1 remains the same
∂s∂v=t2t−s×0
Any expression multiplied by 0 equals 0
∂s∂v=t2t−0
Removing 0 doesn't change the value,so remove it from the expression
∂s∂v=t2t
