From the trigonometry:
tan θ = (sin θ) / (cos θ)
cot θ = (cos θ) / (sin θ)
∴ tan θ + cot θ = (sin θ) / (cos θ) + (cos θ) / (sin θ)
= [ sin² θ + cos² θ]/( sin θ cos θ) = 1 /( sin θ cos θ )
note : sin² θ + cos² θ = 1

Answer: 48 and 12.
Step-by-step explanation:
Let the smaller number is x. Hence, the larger number is 4*x.
The difference between 2 number is 36.
So,
4*x-x=36
3*x=36\ |:3
x=12.
4*x=12*4
4*x=48.
Good luck an' have a nice day!
