Verify the identity. Justify each step.
pishuonlain [190]
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

A store finds that the number of shirts sold increases each week. In the first week, only 15 shirts were sold. In the next week,
nikklg [1K]

Answer:

a_n=8+7n

Step-by-step explanation:

No. of T-Shirts sold in first week = 15

No. of T-Shirts sold in second week = 22

No. of T-Shirts sold in third week = 29

The number of shirts sold each week represents an arithmetic sequence.

15,22,29,....

So, a = first term = 15

d = common difference = 22-15= 29-22= 7

Formula of nth term :a_n=a+(n-1)d

a is the first term

d is the common difference

n is the number of term

Now substitute the values in the formula :

a_n=15+(n-1)7

a_n=15+7n-7

a_n=8+7n

Where n is the number of weeks

Hence the explicit rule for the arithmetic sequence that defines the number of shirts sold in week n is a_n=8+7n
