*cost tant
* cost csct
To simplify the expression "cost tant," it seems like you may be referring to trigonometric functions. Please note that "tant" is not a recognized trigonometric function. The standard trigonometric functions are sine (sin), cosine (cos), and tangent (tan).
If you meant to write "cost tan," we can simplify it. The cosine of the tangent of an angle can be simplified using trigonometric identities. Here's how to do it:
1. Start with the expression "cost tan."
2. Recall that the tangent of an angle is defined as the sine of the angle divided by the cosine of the angle: tan(x) = sin(x) / cos(x).
3. Substitute this definition into the expression: cos(tan(x)) = cos(sin(x) / cos(x)).
4. Since cosine is a multiplicative function, we can separate it: cos(tan(x)) = cos(sin(x)) / cos(cos(x)).
5. Finally, simplify any remaining trigonometric expressions using appropriate identities or a calculator.
As for the expression "cost csct," there seems to be a typo or an incorrect usage of trigonometric functions. There is no recognized trigonometric function called "csct." Please check your expression and specify the correct functions involved, if possible.
