Homework Statement
I am little confused. Value of used to be
sin(0) = 0 = cos(1)
sin(1) = 1 = cos(0)
Homework Equations
The Attempt at a Solution
Now when I use google calculator I use rad or degree I do not get solid 1 and 0.
for example
sin(0)= 0 deg =0rad
sin(1)= .841 deg = 0.017 rad
cos(0)= 0 deg = 0 rad
cos(1) = 0.54 deg = 099 rad
1-besides when when at the point when sin is zero should con not be one ? and vise versa ?
2-do the values of cosh and sinh also go zero and one on some point ?
3-what is good reliable way to check those values ?Thank you.
