Finding the following function correct to five decimal places?

Question

a. sin 22 degrees 43'

b. cos 44 degrees 56'

c. tan 11 degrees 37'

d. cot 19 degrees 0' 25''

can you guys please explain step by step thank u

Answer 1

The answerer before me said you can't answer this because half of it is in radian form (sin/cos) and the other half is in degree mode - this is absolutely false, you can calculate sin/cos for degrees or radians, just make sure your calculator is in degree mode.

There are 60 minutes in a degree, 60 seconds in a minute, so

a. 22 degrees, 43' = (22+43/60) degree

Just enter in your calculator (make sure you enter brackets)

(22 + 43/60) sin

If your calculator doesn't have brackets, then enter:

22 + 43/60 = sin

If your calculator is more advanced, where you enter the function first then enter:

sin (22 + 43/60)

answer: 0.38617

Do the same for b, c

b. cos(44 + 56/60) = 0.70793

c. tan (11 + 37/60) = 0.20557

d.

19 degrees, 0' 25" = (19 + 0/60 + 25/(60x60)) degrees

= (19 + 25/3600) degrees

cot (19 + 25/3600) = cos (19 + 25/3600) / sin (19 + 25/3600)

cot (19 + 25/3600) = 2.90307
