Masukkan nilai dan tekan Kira untuk melihat keputusan.

Formula

sin⁡θ=opphyp, cos⁡θ=adjhyp, tan⁡θ=sin⁡θcos⁡θ\sin\theta = \frac{\text{opp}}{\text{hyp}},\ \cos\theta = \frac{\text{adj}}{\text{hyp}},\ \tan\theta = \frac{\sin\theta}{\cos\theta}

SOH CAH TOA in a right triangle, extended to every angle by the unit circle.

Cara menggunakan kalkulator ini

  1. Enter the angle and choose degrees or radians.
  2. Multiples of 30° and 45° give exact answers; other angles give rounded decimals.

Contoh berserta jalan kerja

Trig values of 30°

sin 30° = 1/2, cos 30° = √3/2, and tan 30° = sin/cos = √3/3.

Soalan lazim

Why is tan 90° undefined?

tan = sin/cos and cos 90° = 0, so the division is undefined.

Degrees or radians?

A full turn is 360° or 2π radians. Make sure the unit matches your problem.
