Therefore, tan 180° = 0. Or. tan 180° = tan(180° – 0) = – tan 0° = 0 {since tan 0° = 0} This value is taken from the trigonometry table. Method 2: In this method, we directly substitute the values of sin 180° and cos 180° from the table values of trigonometry ratios in the tan formula. tan 180° = sin 180°/cos 180° = 0/(-1) = 0

In trigonometry, tan of an angle is the ratio of the sine and cosine of the same angle. tanθ = sinθ cosθ. ∴ tan 180 ° = sin 180 ° cos 180 ° ⇒ = 0-1 [∵ sin 180 ° = 0 and cos 180 ° =-1] ⇒ = 0. Hence, tan 180 ° is equal to 0.

Find the value of tan 45 o + 2 cos 60 o – sec 60 o. Solution: From the trigonometry table, tan 45 o = 1, cos 60 o = ½ and sec 60 o = 2. Therefore, tan 45 o + 2 cos 60 o – sec 60 o = 1 + 2 × ½ – 2 = 1 + 1 – 2 = 0. Example 2: Find the value of sin 75 o. Solution: We can write, sin 75 o = sin (45 o + 30 o) = sin 45 o cos 30 o + cos 45 o ...

Express the ratios cos A, tan A and sec A in terms of sin A. Prove that sec A (1 – sin A)(sec A + tan A) = 1. Find the value of 7 sec 2 A – 7 tan 2 A. Show that (sin A + cosec A) 2 + (cos A + sec A) 2 = 7 + tan 2 A + cot 2 A; Using these identities, we can solve various mathematical problems.

When we find sin cos and tan values for a triangle, we usually consider these angles: 0°, 30°, 45°, 60° and 90°. It is easy to memorise the values for these certain angles. The trigonometric values are about the knowledge of standard angles for a given triangle as per the trigonometric ratios (sine, cosine, tangent, cotangent, secant and ...

The value of cot A + tan (180 ° + A) + tan (90 ° + A) + tan (360 ° − A) is Q. Prove that cot A + tan ( 180 ∘ + A ) + tan ( 90 ∘ + A ) + tan ( 360 ∘ − A ) = 0 .

May 13, 2023 · Hence, tan θ + tan ( 90 ° - θ ) = s e c θ · s e c ( 90 ° - θ ) is proved.Since 180° lies on the negative x-axis, the final value of tan 180° is 0.
