Question

If o°<@< 90° and Cos@ = 4/5 find the value of tan (360°-0)​

Answer 1

Answer:

If n is a negative integer then the trigonometrical ratios of (n ∙ 360° - θ) are equal to the ... cos (n ∙ 360° - θ) = cos θ;. tan ( n ... sin 270° = sin (360 - 90)° 

Answer 2

Step-by-step explanation:

The value of Tan 360° could be solved by

Tan 360°= tan(270°+90)

= -cot (90) ( since tan (270°+90°) lies into the fourth quadrant and it's value is negative and tan(270+Φ)= -cot(Φ) )

And the value of cot 90° is 0 so it doesn't matter even if it is negative so value of -cot 90° is zero.

So the value of tan360° is 0.

There are even many other ways of solving it lik you could either keep it in terms of tan Φ or by dividing sinΦ by cos Φ and replacing Φ by 360°.

Hope it helps.
