An irrational number has an infinite number of decimal places. It never ends.
If the decimal ever ended, then the number would be rational.
The same value as cosα
cosα=sin(90-α) and vice versa
sinα=cos(90-α)
The answer would be A. Make sure you also use BEDMAAS, and take care of the brackets first
In standard form, zero is always on the right:
y = 12 - x^4
y + x^4 - 12 = 0
End behavior:
As x approaches ∞, y approaches -∞
As x approaches -∞, t approaches -∞
