A differential equation is an equation that contains an unknown function and one or more of its derivatives.
The order of a differential equation is the order of the highest derivative that occurs in the equation.
An initial condition is a condition of the form
2/3
4/3-one books, 2 nights
6/3-2 books, 3 nights
8/3
10/3-3 books, 5 nights
12/3=4 books in 6 nighs
(4x - y)/(2y + x) when x = 3 and y = 3 is
(4(3) - 3)/(2(3) + 3) = (12 - 3)/(6 + 3) = 9/9 = 1
Cos 105 will also be -0.26
csc 105 = 1.03
M=72 that’s the best I can give you lol not sure if that helps any
