Use a calculator to find the values of the inverse trigonometric functions. Round to the nearest degree. sin–1 (two-thirds) = ° tan–1(4) = ° cos–1(0.1) = °

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Sum is 17 and their difference is 3
