Question

Tg60×Tg50×Tg45×Tg40×Tg30

Answer 1

Tg60 = √3,  
tg45 = 1,  
tg30 = 1/√3.  
Найдем tg50 · tg40 = tg(90 - 40) * tg40 = ctg40 * tg 40 = 1.
Значит данное произведение равно √3 * 1 * 1 * 1/√3 = 1.

Answer 2

The expression "Tg60×Tg50×Tg45×Tg40×Tg30" appears to involve trigonometric functions. Here, "Tg" likely represents the tangent function, but it's essential to clarify whether these angles are in degrees or radians because the trigonometric functions can operate in either unit.

If these angles are in degrees, then the expression would involve finding the product of the tangent values of these angles:

Tg60 × Tg50 × Tg45 × Tg40 × Tg30 ≈ 1.7321 × 1.19175359 × 1 × 0.8391 × 0.577 ≈ 1.302

The approximate result is 1.302.

Please ensure that the angles are in degrees when using this calculation. If the angles are in radians, you should convert them to degrees first using the relationship: radians = degrees × (π/180).
