\[\lim_{x \to \frac{3\pi}{2}} \frac{1 + {cosec}^3 x}{\cot^2 x}\]

Table below shows the frequency f with which 'x' alpha particles were radiated from a diskette 

If a variable X takes values 0, 1, 2,..., n with frequencies ⁿC₀, ⁿC₁, ⁿC₂ , ... , ⁿC_n, then write variance X.

\[\lim_{x \to 0} \frac{\sin 2x}{e^x - 1}\] 

\[\lim_{x \to 0} \frac{\log \left( a + x \right) - \log a}{x}\]

\[\lim_{x \to 0} \frac{\log \left( 3 + x \right) - \log \left( 3 - x \right)}{x}\] 

\[\lim_{x \to 0} \frac{8^x - 2^x}{x}\]

Let x₁, x₂, ..., x_n be values taken by a variable X and y₁, y₂, ..., y_n be the values taken by a variable Y such that y_i = ax_i + b, i = 1, 2,..., n. Then,

If two variates X and Y are connected by the relation \[Y = \frac{a X + b}{c}\] , where a, b, c are constants such that ac < 0, then
