Question

Electrical & Electronic Engineering, Physics often use mathematical modelling to represent in theory real life situations. An example of this is a current against time graph where the area under the curve represents the amount of charge, or a velocity time graph where the area under the curve gives the distance travelled. can you check this question is it correct or not i need detailed answer of this

(2) An electrical signal can be modelled by the following Power (Watts)
verses time t (s)
by the equation:-
P =
1.2,
0.1
4πt
5
sin- dt
By using definite integration evaluate the above expression, hence
determine the
energy dispersed (J)
N.B. make sure your calculator is in radians mode.
