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

A movie theater has a seating capacity of 333. The theater charges $5.00 for children, $7.00 for students,
pantera1 [17]

Answer:

182 children, 91 adults, 60 students

Step-by-step explanation:

The quantity of adults is x, then the quantity of children are 2x,  the quantity of students is 333-x-2x=333-3x. The charge from all adults is 12x, students gave 7*(333-3x), children gave 5*2x=10x, the sum of all money is 2422

12x+ 7(333-3x)+10x=2422

12x+2331-21x+10x=2422

2331+x=2422

x=91- the amount of adults

1) 91*2=182- the amount of children

333-91-182= 60- the amount of students
