Step-by-step explanation:
"inverse sine" may refer to either a single values function (the principal value -- common in introductory courses) or to a "multivalued function". We know that sin(π6)=12 and so, sin(−π6)=−12 . Therefore, the (principal) inverse sine of −12 is −π6
The period of the function f(x) = cos4x + tan3x is
π3
π
None of these
π2
If 3sin–1(2x1+x2) −4cos–1(1–x21+x2)+2tan–1(2x1–x2)=π3. Then, x=.
