Question
Differentiate the following function with respect to $(\text{x})$:
$2\sec\text{x}+3\cot\text{x}-4\tan\text{x}$
$2\sec\text{x}+3\cot\text{x}-4\tan\text{x}$
$\frac{\text{d}}{\text{dx}}(2\sec\text{x}+3\cot\text{x}-4\tan\text{x})$
$=2\frac{\text{d}}{\text{dx}}(\sec\text{x})+3\frac{\text{d}}{\text{dx}}(\cot\text{x})-4\frac{\text{d}}{\text{dx}}(\tan\text{x})$
$=2\sec\text{x}\tan\text{x}-3\text{cosec}^2\text{x}-4\sec^2\text{x}$
