Thecosecant ( ), secant ( ) and cotangent ( ) functions are 'convenience' functions, just the reciprocals of (that is 1 divided by) the sine, cosine and tangent. So. Notice that cosecant is the reciprocal of sine, while from the name you might expect it to be the reciprocal of cosine! Everything that can be done with these convenience Contoh2 - Cara Penggunaan Rumus Aturan Cosinus. Dua kapal A dan B meninggalkan pelabuhan P bersama-sama. Kapal A berlayar dengan arah 30 o dan kecepatan 30 km/jam, sedangkan kapal B berlayar dengan arah 90 o dan kecepatan 45 km/jam. Jika kedua kapal berlayar selama 2 jam, maka jarak kedua kapal tersebut adalah . Step1: Identify The Quadrant. Since we're dealing with the unit circle with tan, we will need to use the values we've memorized from sine and cosine, and then solve. First, however, we need to figure out what quadrant we're in so we know whether our answers for sine and cosine will be positive or negative. tan45^@)=1 sin(45^@)=sqrt2/2 cos(45^@)=sqrt2/2 45^@ is a special angle, along with 30^@, 60^@, 90^@, 180^@, 270^@, 360^@. tan(45^@)=1 sin(45^@)=sqrt2/2 cos(45 Learnhow to use trigonometric functions inside Google Spreadsheet with Sine, Cosine and Tangent functions. Tangent90 degrees is evaluated as undefined because tan of an angle is equal to the ratio of sin and cos of same angle. Since, sin 90 = 1 and cos 90 = 0, therefore; Tan 90 = sin 90/cos 90. = 1/0. = ∞. As we have got the result as infinity, and we cannot define infinity, therefore tan 90 is undefined. .
