Hello,
When you compose 2 reciprocals functions, you will find 1.
ex f(x)=√x and g(x)=x² , x>=0
so that g(f(x))=(√x)²=x
sin(cos(0))=sin(1)=0,84147... rad and not 1.
Reciprocal function of sin (x) is arcsin(x).
Reciprocal function of cos (x) is arccos(x).
1.3, 1 1/3, 1.34
The decimal version of 1 1/3 is 1.333 (so on)
so 1.3 is less than 1.333 and 1.333 is less than 1.34
1.3<1.333<1.34
.27 repeating.... you have to put three on the inside and 11 outside, so 11 goes into 3 zero times so put a zero at the top. Write a zero underneath and subtract 3-0 (obviously 3) and put a decimal point after the first three under the sign and the 0 above it. Add a zero after the threes decimal, and carry it down to the bottom most 3 to have 30. 11 goes into 30 two times so write a 2 at the top. Subtract the 30-22 at the bottom and get 8. Add another 0 after the 3 ( so now 3.00) and carry it to the 8 (80). 11 goes in 7 times, 77. So 7 on top and 80-77= 3 below. Add another zero to repeat process if necessary, but otherwise it repeats, just so you know ;) hope this helps
The answer is 3 1/3 + 2 1/3 = 5 2/3
