Tanθ + cotθ = 1/sinθcos<span>θ

since we know that;

tan</span>θ = sinθ/cos<span>θ, and

cot</span>θ = cosθ/sin<span>θ

now when we add tan</span>θ and cot<span>θ and replace their values;

tan</span>θ + cot<span>θ=sin</span>θ/cosθ + cosθ/sin<span>θ

</span>For a common denominator to add those two fractions, the obvious choice is sinθ.cosθ , so

tanθ + cotθ = sin²θ/sinθcosθ + cos²θ/sinθcosθ =sin²θ + cos²θ / sinθcosθ

now we can use the identity that;

sin²θ + cos²θ = 1

So,

tanθ + cotθ = 1/sinθcosθ

Question is in picture below ​
klasskru [66]

Answer:

\frac{y - 18}{x - 1}  =  \frac{23 - 18}{1.5 - 1}  =  \frac{5}{0.5}  = 10 \\ y - 18 = 10(x - 1)  = 10x - 10 \\ y = 10x  + 18 - 10 = 10x + 8 \\  \boxed{f(x) = 10x + 8}

<h2>A. is the right answer.</h2>

hope this helps.
