Inverse Circular (trigonometric) Functions
Part-I
Steps:
- Turn on radian mode as you are solving trigonometric problems to get less error, by pressing Shift + Mode + 4.
- Copy the question with maximum and effective uses of brackets. Only () small brackets are available there, so use them repeating as required.
- If there is variable or unknown constant in the given question, put suitable value for that variable/constant to get different values of option in order to identify exact option.
- Watch above video for detail explanation and examples.
