Answer:

\cot \theta =  \frac{8}{15} \\\\\sec \theta =  \frac{17}{8} \\\\\csc \theta =  \frac{17}{15}

Step-by-step explanation:

\huge \tan \theta =  \frac{15}{8} ...(given) \\  \\  \huge \because \:  \cot \theta =  \frac{1}{ \tan \theta} \\  \\  \huge \therefore \: \cot \theta =  \frac{1}{ \frac{18}{8} } \\  \\  \huge \therefore \:  \cot \theta =  \frac{8}{15}  \\  \\ also \\ \huge  \sec \theta =  \frac{17}{8}  \\

I need help solving this problem. <img src="https://tex.z-dn.net/?f=4x%20cos%20%5E%7B-1%7D%20%282x%2B4%29-%20%5Csqrt%7B3-3%20x%5

Given:
f(x)=4xcos^{-1}(2x+4)-\sqrt{3-3x^2}

Using
\frac{d}{dx}cos^{-1}(x)=-\frac{1}{\sqrt{1-x^2}}
we derive
\frac{d}{dx}4xcos^{-1}(2x+4)
=4cos^{-1}(2x+4)-\frac{8x}{\sqrt{1-(2x+4)^2}}

Similarly, using
\frac{d}{dx}\sqrt{x}=\frac{1}{2\sqrt{x}}
we derive
\frac{d}{dx}(-\sqrt{3-3x^2})
=\frac{3x}{\sqrt{3-3x^2}}

Therefore, the derivative is
f'(x)=\frac{d}{dx}(4xcos^{-1}(2x+4)-\sqrt{3-3x^2})
=4cos^{-1}(2x+4)-\frac{8x}{\sqrt{1-(2x+4)^2}}+\frac{3x}{\sqrt{3-3x^2}}
