2017年11月6日 · This is only an approximation, but I think you are using 37° because it is an angle of a 3-4-5 triangle (approximately).

The value of logtan 17∘+logtan 37∘+logtan 53∘+logtan 73∘ is

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 ...
