A vertical asymptote occurs when a function approaches infinity. This is usually the result of dividing by zero. So find the 'x' value that causes the denominator to reach zero.
tan x = sin x / cos x -----> cos x = 0 when x = pi/2, 3pi/2
cot x = cosx / sinx -------> sin x = 0 when x = 0,pi
sec x = 1/cos x --------> cos x = 0 when x = pi/2, 3pi/2
csc x = 1 /sin x --------> sin x = 0 when x = 0,pi
Answer:
x=4
Step-by-step explanation:
4x+7=23
4x=23-7
4x=16
x=16÷4
x=4
Answer:The answer is c
Step-by-step explanation:
Multiply both side is the equation by -1.
Sum the equations vertically to eliminate at least one variable
Divide both sides of the equation by 3
Substitute the given value of y into the equation 2x+3y=8
and then solve for x
Answer:
BC = 13
Step-by-step explanation:
Pitagoras:
H^2= 5^2 + 12^2
H^2=25 + 144
H^2= 169
H= V 169 ---- square root
H= 13 -------BC
