Question

TT COS 60°/9 sin 2°
The value of
to nearest integer is
approximately :-​

Answer 1

Answer:

$5$

Explanation:

• Trigonometric functions of angles are used as variables in the trigonometric equations. In trigonometric equations, the angle of trigonometric functions like Sin, Cos, and Tan is a variable.
• The trigonometric equations have solutions, which are known as main solutions and general solutions, just like general polynomial equations do.
• $\pi \cos ( 60 ) = 1.57$
• $9 \sin ( 2 ) = 0.314$
• $\pi \cos ( 60 ) / 9 \sin ( 2 ) = 1.57/0.314$
• $\pi \cos ( 60 ) / 9 \sin ( 2 ) = 5$

Answer 2

Answer:

5

Explanation:

Trigonometric functions of angles are used as variables in the trigonometric equations.

In trigonometric equations, the angle of trigonometric functions like Sin, Cos, and Tan is a variable.

The trigonometric equations have solutions, which are known as main solutions and general solutions, just like general polynomial equation

$\pi \cos ( 60 ) = 1.57</p><p> \\ πcos(60)=1.57</p><p>9 \ \\sin ( 2 ) = 0.3149</p><p> \\ sin(2)=0.314$

$\frac{\pi \cos ( 60 )}{9 \sin(2) } </p><p>$

$= \frac{3.14 \times 1.57}{0.314\times 9 }$

= 5
