The infinite series description of trig functions is much neater when the argument is radians. For example, for small angles, sin(x) ≈ x when x is in radians. You could say that radians is the "natural" measurement unit for angles, just as "e" is the "natural" base of logarithms.
If the angle measure were degrees or grads or arcseconds, obnoxious scale factors would show up everywhere.
Answer:
Step-by-step explanation:
We want to simplify:
We convert to improper fraction to get:
We now deal with the parenthesis by multiplying with the reciprocal of 2.
This gives:
We multiply to get:
This simplfies to:
We write as mixed number

Answer:
48cm
Step-by-step explanation:
96/12=8
This means that 8 is the factor by which the diagram and the actual ramp vary
so then you multiply 8 times the height on the diagram to find the true height
8x6=48
