To answer this question we observe that y is the product of x^2 and sin(x), so we use the product rule. Then dy/dx = 2x * sin(x) + cos(x) * x^2 The resulting equation can be tidied up by factoring out x a...
To solve this integral you should use the integration by parts formula, which is uv - integral of vu'. First let x^2 be u, therefore u'(the differential of x^2) = 2x, v' = e^x and therefore v (integral of...
Use the moon method.
E.g. (x+1)(x+2)
multiply x with x
multiply x with 2
mutiply 1 with x
multiply 1 with 2
2u-32=53=15, 2u=15+6. Therefore, u=10.5m/s. This is a standard type of question, it is simply about conservation of momentum. Momentum (p) is equal to massvelocity. Initially, the first body ...
A base is a proton acceptor.
Amines work as bases due to the electronegativity of the nitrogen atom. The lone pair in the nitrogen atom is filled in a 2p(z) orbital, in phenylamine, the p orbital ...
