Sec^2 theta/tan theta = sec theta x csc theta
Andreas93 [3]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

• tan x = \frac{sinx}{cosx}

• sec x = \frac{1}{cosx}, csc x = \frac{1}{sinx}

Consider the left side with x = Θ

\frac{sec^2x}{tanx}

=\frac{1/cos^2x}{\frac{sinx}{cosx} }

= \frac{1}{cos^2x} × \frac{cosx}{sinx}

= \frac{1}{cosxsinx}

= \frac{1}{cosx} × \frac{1}{sinx}

= secxcscx = right side ⇒ verified

8_murik_8 [283]

This is one of those cases where you have to believe that a minus times a minus is a plus.

114 - - 39 = 153 degrees. The freezing of mercury is 153 degrees cooler than the freezing point of alcohol. I would check your descriptions. Did you mean boiling point of Alcohol?
