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

ddd [48]

Given:

The equation is

\left(z+\dfrac{6}{7}\right)+\dfrac{2}{14}=-1

To find:

The solution of the given equation.

Solution:

We have,

\left(z+\dfrac{6}{7}\right)+\dfrac{2}{14}=-1

It can be written as

\left(z+\dfrac{6}{7}\right)+\dfrac{1}{7}=-1

\left(z+\dfrac{6}{7}\right)=-1-\dfrac{1}{7}

Multiply both sides by 7.

7z+6=-7-1

7z+6=-8

7z=-8-6

7z=-14

Divide both sides by 7.

z=\dfrac{-14}{7}

z=-2

Therefore, the value of z is -2.

SOLVE FOUR AND FIVE I WILL GIVE BRAINLIST!
asambeis [7]

Answer:

see explanation

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

(4)

Here d = 18, thus

C = 18π in

(5)

Here C = 50π, thus

πd = 50π ( divide both sides by π )

d = 50 in

The radius r is one half of the diameter , thus

r = 50 ÷ 2 = 25 in
