Answer 2

To determine the correctness of the given values, let's use the trigonometric Pythagorean identity:

sin^2(x) + cos^2(x) = 1

where "x" is the angle in question.

Now, we are given the values: sin(a) = 1.4 cos(a) = -0.7

Let's check if these values satisfy the Pythagorean identity:

sin^2(a) + cos^2(a) = 1.4^2 + (-0.7)^2 = 1.96 + 0.49 = 2.45

The result is not equal to 1, as it should be for the Pythagorean identity to hold. Therefore, the given values are incorrect.

Please double-check the values of sine (sin) and cosine (cos) that you have provided. Keep in mind that the sine and cosine values typically range from -1 to 1. If the values are within this range, the Pythagorean identity will be satisfied.
