The pythagorean theorem works for all right triangles. Just make sure it IS a right triangle.
Sin 30 = 1/2
tan 45 = 1
Cosec 60 = 2 / √3 = 2√3 / 3
cot 45 = 1
Cos 60 = 1/2
sec 30 = 2 / √3 = 2√3 / 3
_______________________________
[ 1/2 + 1 - 2√3/3 ] ÷ [ 1 + 1/2 - 2√3/3 ] = <em>1</em>
The face and denominator of the fraction are exactly the same thus the answer is 1 .

Answer:
Step-by-step explanation:
Let be 
, the range of the function corresponds to the set of values of 
. The sine function is a bounded function between -1 and 1. Hence, the range of the function is:
