Solve ds/dt=cos(2t)+sin(t) explicitly when t=π and s = 1.

s = ½sin(2x) - cos(x)

Step-by-step explanation:

s = sin(2t)/2 - cos(t) + c

1 = sin(2pi)/2 - cos(pi) + c

1 = 0 - (-1) + c

1 = 1 + c

c = 0

s = ½sin(2x) - cos(x)

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
