Question

HEEEEEELP ME! 1-tg(бетта)+1/cos(бетта)

Answer 1

$\frac{2cos \frac{ \alpha }{2} }{cos \frac{ \alpha }{2}+sin \frac{ \alpha }{2} }$
 ну в смысле не альфа а бетта...

Answer 2

It looks like you've entered a mathematical expression. The expression you've provided is 1-tg(β)+1/cos(β). Let's break it down step by step.

Step 1: Understanding the Expression

The expression you've provided is: 1 - tg(β) + 1/cos(β)

Step 2: Evaluating the Expression

To evaluate the expression, we need to understand the trigonometric functions involved. The expression includes the tangent (tg) and cosine (cos) functions.

Step 3: Evaluating the Tangent and Cosine Functions

The tangent function (tg) is defined as the ratio of the sine to the cosine of an angle. The cosine function (cos) represents the ratio of the adjacent side to the hypotenuse in a right-angled triangle.

Step 4: Substituting Values

To evaluate the expression further, we would need a specific value for the angle (β) in order to substitute it into the trigonometric functions.

If you have a specific value for the angle (β), please provide it so that we can proceed with evaluating the expression further.
