Answer 1

Right option is (c) To find the tan of a number

Best explanation: The tan() function is used to find the tangent of an angle. It takes one argument; the angle whose tangent is to be found out. This number is to be entered in the radian format and not the degree format. This function can accept the float datatype and gives the output in the double datatype.
