WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. WebMar 17, 2024 · Divide your sine values by the cosine values to fill the tangent row. Simply speaking, tangent = sine/cosine. Therefore, for every angle, take its sine value and divide it by its cosine value to calculate the corresponding tangent value. To take 30° as an example: tan 30° = sin 30° / cos 30° = (√1/2) / (√3/2) = 1/√3. portable dvd player with usb for car
