4cos^2 60=3-4cos 60
You asked:
Investigate the equation: \(4 {\cos\left( 60 \right)}^{2} = 3 - 4 \cos\left( 60 \right)\).
MathBot Answer:
This equation has no unknown quantities, so it is either true or false.
This equation is false because the left-hand side is not equal to the right-hand side.
The left-hand side of the equation is:
\[4 {\cos\left( 60 \right)}^{2} = 4 \cos^{2}{\left(60 \right)}\]The right-hand side of the equation is:
\[3 - 4 \cos\left( 60 \right) = 3 - 4 \cos{\left(60 \right)}\]
