Value of Tan 15 Degrees - Calculation Using Trigonometry …
From the above table, we have the values of tan, sin and cos ratios for 0°, 30°, 45°, 60 ° and 90°. Now, by using these values, we have to find the value of tan (15°). Let’s get started, Tan 15° = Tan(45 – 30)° By the trigonometry formula, we know, Tan (A – B) = (Tan A – Tan B) /(1 + Tan A Tan B) Therefore, we can write,
Sin Cos Tan Values (Formula, Table & How to Find) - BYJU'S
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 ...

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 ...
