Question
What is the value of tan 570°
?Solution
To find tan 570Âș , we reduce the angle by subtracting multiples of 360Âș until we get an equivalent angle between 0Âș and 360Âș. 570Âș - 360Âș = 210Âș Therefore, tan(570Âș) = tan(210Âș) Now, tan(210Âș) = tan(180Âș + 30Âș) Using the formula tan(180Âș + Ξ) = tan(Ξ) , we get: tan(210Âș) = tan(30Âș) And we know: tan(30Âș) = 1/â3 However, since 210Âș is in the third quadrant where tan is positive, we have: tan(210Âș) = tan(30Âș) = 1 / â 3 Therefore, the value of tan(570Âș) is 1 / â 3  .
