Answer:
The domain is the input values on the x-axis and range is input values on the y-axis
Step-by-step explanation:
Basically, domain is the horizontal values and range is the vertical ones.
Step-by-step explanation:
LHS= 1 + cot^2A/1+cosecA
=(1+cosecA + cot^2A)/1+cosecA
{By using basic trigonometric theorem cot^2A = cosec^2A - 1}
=(1+cosecA + cosec^2A - 1)/(1+cosecA)
=(cosecA + cosec^2A)/(1+cosecA)
=[cosecA (1+cosecA)]/(1+cosecA)
{Cancelling 1+cosecA}
=cosecA
Answer:
-x -9y
Step-by-step explanation:
-(3x+y)+2(x-4y)
-3x -y +2x -2*4y
-x -y -8y
-x -9y
