Solution for s(t)=4sin(pi*t)+5cos(pi*t) equation:


Simplifying
s(t) = 4sin(pi * t) + 5cos(pi * t)

Multiply s * t
st = 4sin(pi * t) + 5cos(pi * t)

Multiply ip * t
st = 4ins(ipt) + 5cos(pi * t)

Multiply ins * ipt
st = 4i2npst + 5cos(pi * t)

Multiply ip * t
st = 4i2npst + 5cos(ipt)

Multiply cos * ipt
st = 4i2npst + 5ciopst

Reorder the terms:
st = 5ciopst + 4i2npst

Solving
st = 5ciopst + 4i2npst

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-5ciopst' to each side of the equation.
-5ciopst + st = 5ciopst + -5ciopst + 4i2npst

Combine like terms: 5ciopst + -5ciopst = 0
-5ciopst + st = 0 + 4i2npst
-5ciopst + st = 4i2npst

Add '-4i2npst' to each side of the equation.
-5ciopst + -4i2npst + st = 4i2npst + -4i2npst

Combine like terms: 4i2npst + -4i2npst = 0
-5ciopst + -4i2npst + st = 0

Factor out the Greatest Common Factor (GCF), 'st'.
st(-5ciop + -4i2np + 1) = 0

Subproblem 1

Set the factor 'st' equal to zero and attempt to solve: Simplifying st = 0 Solving st = 0 Move all terms containing s to the left, all other terms to the right. Simplifying st = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(-5ciop + -4i2np + 1)' equal to zero and attempt to solve: Simplifying -5ciop + -4i2np + 1 = 0 Reorder the terms: 1 + -5ciop + -4i2np = 0 Solving 1 + -5ciop + -4i2np = 0 Move all terms containing s to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -5ciop + -1 + -4i2np = 0 + -1 Reorder the terms: 1 + -1 + -5ciop + -4i2np = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -5ciop + -4i2np = 0 + -1 -5ciop + -4i2np = 0 + -1 Combine like terms: 0 + -1 = -1 -5ciop + -4i2np = -1 Add '5ciop' to each side of the equation. -5ciop + 5ciop + -4i2np = -1 + 5ciop Combine like terms: -5ciop + 5ciop = 0 0 + -4i2np = -1 + 5ciop -4i2np = -1 + 5ciop Add '4i2np' to each side of the equation. -4i2np + 4i2np = -1 + 5ciop + 4i2np Combine like terms: -4i2np + 4i2np = 0 0 = -1 + 5ciop + 4i2np Simplifying 0 = -1 + 5ciop + 4i2np The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
