sec 40° - √3 cosec ( 2×40°) = 4
You asked:
Investigate the equation: \(\sec\left( 40^{\circ} \right) - \sqrt{3} \cdot \csc\left( 2 \cdot 40^{\circ} \right) = 4\).
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:
\[\sec\left( 40^{\circ} \right) - \sqrt{3} \cdot \csc\left( 2 \cdot 40^{\circ} \right) = - \sqrt{3} \csc{\left(80 ^\circ \right)} + \sec{\left(40 ^\circ \right)}\]The right-hand side of the equation is:
\[4\]
