WebIn other words, the rth derivative of the mgf evaluated at t = 0 gives the value of the rth moment. Theorem 3.8.1 tells us how to derive the mgf of a random variable, since the mgf is given by taking the expected value of a function applied to the random variable: MX(t) = E[etX] = ∑ i etxi ⋅ p(xi) Web20 dec. 2024 · and sketch the curve, the unit tangent and unit normal vectors when t = 1. Solution First we find the unit tangent vector T ( t) = i ^ + 2 t j ^ 1 + 4 t 2. Now use the quotient rule to find T ′ ( t) T ′ ( t) = ( 1 + 4 t 2) 1 2 ( 2 j ^) …
