Fine the exact value. tan(60°)+tan(225°)
2 answers:
tangent 60 is √3 on the unit circle and tangent 225 is 1. So 1+√3 is the exact value of tan 60 plus tan 225
We need to find exact value of Tan 60+Tan 225°
We apply the reference angle by finding the angle with equivalent trigonometrical values in the first quadrant.
On the trig unit circle,
tan 225 = tan (45 + 180) = tan 45 = 1.
The exact value of tan(45) is 1.
The exact value of Tan 60° = .
Substituting Tan225 and Tan60 values we have:
Tan 225°+Tan60°= 1+

Answer:
Step-by-step explanation:
When simplifying an exponent a way to do is to expand the exponent. This means that it will now be
Whenever you see an x or y on the numerator and denominator cross it out because it is the same thing as 1
When you cross out all of the x's and y's the only variable left is y in the denominator. This means that the answer is
