Question

Sin(25)=sin(35)=cos(25)=cos(35)=sin(3п/8)=cos(82)=cos(п/3)=​

Answer 1

sin(25)= -0,132352

sin(35)= -0,428183

cos(25)= 0,991203

cos(35)= -0,903692

$\sin( \dfrac{3\pi}{8} ) = \dfrac{ \sqrt{2 + \sqrt{2} } }{2}$

cos(82)= 0,949678

$\cos( \dfrac{\pi}{3} ) = \dfrac{1}{2}$

Answer 2

It appears that there is a misunderstanding in your statement. The trigonometric functions do not have equal values for the angles you mentioned. Here are the correct values:

1. sin(25) is a specific value for the sine function at an angle of 25 degrees or 25π/180 radians.

2. sin(35) is a specific value for the sine function at an angle of 35 degrees or 35π/180 radians.

3. cos(25) is a specific value for the cosine function at an angle of 25 degrees or 25π/180 radians.

4. cos(35) is a specific value for the cosine function at an angle of 35 degrees or 35π/180 radians.

5. sin(3π/8) is a specific value for the sine function at an angle of 3π/8 radians.

6. cos(82) is a specific value for the cosine function at an angle of 82 degrees or 82π/180 radians.

7. cos(π/3) is a specific value for the cosine function at an angle of π/3 radians (which is equivalent to 60 degrees).

Each of these trigonometric functions will have different numerical values, and they are not equal to each other. You can calculate these values using a calculator or a trigonometric table.
