Kikokotoo cha Trigonometria (sin, cos, tan)

Weka pembe ili kupata sine, cosine na tangent yake. Pembe maalum zinaonyeshwa kwa usahihi.

Tokeo

Weka thamani kisha bonyeza Kokotoa ili kuona tokeo.

Fomula

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.

Jinsi ya kutumia kikokotoo hiki

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

Mfano uliotatuliwa

Trig values of 30°

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

Maswali yanayoulizwa mara kwa mara

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.
