Prove that 2sin−1(35)=tan−1(247)

To prove that 2sin^(-1)(35) = tan^(-1)(247), we can use the properties of inverse trigonometric functions and some basic trigonometric identities.

Step 1: Let's start by finding the value of sin^(-1)(35). This represents the angle whose sine is 35. However, the sine function only takes values between -1 and 1, so sin^(-1)(35) is not defined. Therefore, the equation 2sin^(-1)(35) = tan^(-1)(247) is not valid.

Conclusion: The equation 2sin^(-1)(35) = tan^(-1)(247) is not true.
