If a<132, then the number of solutions of (sin-1x)3+(cos-1x)3=aπ3 is
0
1
2
Infinite
Finding the value:
Given: a<132.....(1)
Multiply Equation 1 with π3
Now,
⇒a<132⇒π3a<π332⇒(sin-1x)3+(cos-1x)3<132
Therefore the number of solution is 0
Hence, correct option is (A).
Determine whether the following numbers are in proportion or not:
13,14,16,17
