Cos²x + sin^2x/cscx-cot^2x

Mathematics
1 answer:
Anna [14]3 years ago
5 0

Answer:

1.

Step-by-step explanation:

I am assuming you want to simplify this.

cos^2 x + sin^2 x = 1 and

csc^2 x = 1 + cot^2 x   so  csc^2x - cot^2 x = 1

So the answer is 1/1 = 1.

Answer:

x = 3 and y = 1

Step-by-step explanation:

The given equations are :

6x + 14y = 32  ...(1)

6x - 14y = 4 .....(2)

Add equation (1) and (2) :

6x + 14y + 6x - 14y = 32 + 4

12x = 36

x = 3

Put the value of x in equation (1)

6(3) + 14y = 32

18 + 14y = 32

14y = 32-18

14y = 14

y = 1

Hence, the value of x is 3 and y is 1.
