Définissez la fonction tangente en termes des côtés d'un triangle rectangle.

1. \( -1450^{\circ} \) nin esas ölçüsü aşağıdakilerden hangisi- dir? \( \begin{array}{lllll}\text { A) } 10^{\circ} & \text { B) } 40^{\circ} & \text { C) } 105^{\circ} & \text { D) } 150^{\circ} & \text { E) } 350^{\circ}\end{array} \)

\( [ \sin ( - \theta ) + \cos ( 360 - \theta ) ] [ \cos ( 90 - \theta ) + \frac { \sin \theta } { \tan \theta } ] \)

If the hypotenuse of a right triangle measures 10 units and the length of the opposite side is 6 units, what is the value of the cosecant of the angle opposite the 6-unit side?

Simplity using the sum and difference identity d) \( \cos 3 x \cos 5 x-\sin 3 x \sin 5 x \)

If \( \tan x=m+\frac{1}{m}, 90^{\circ} \leq x \leq 270^{\circ} \) and \( m i^{2}+\frac{1}{m^{2}}=1 \) Calculate the value of \( x \) without the use of a calculator
