If the angle is between 0 degrees and 90 degrees what is cos of tan 7/8?
=.753
if you meant
cos (tan^-1 (7/8)) , yes you are correct to 3 decimal places.
nope its not tan^-1. I need to find cos using what I have which is tan 7/8
To find the value of cos(tan(7/8)), you need to understand the order of operations in mathematics. First, evaluate the value of tan(7/8), and then find the value of cos from that result.
1. Start by finding the value of tan(7/8). This involves taking the tangent of the angle 7/8 in radians or degrees. Since the question does not specify the unit of measurement for the angle (degrees or radians), it is important to clarify this information.
Assuming the angle is given in degrees:
- Convert 7/8 to degrees by multiplying it by 180/π to get approximately 70.057 degrees.
- Then, calculate the tangent of 70.057 degrees using a calculator or mathematical software, which gives you a result of approximately 2.802.
2. After finding the value of tan(7/8), calculate the cosine of that value. Using a calculator, find the cosine of 2.802, which is approximately 0.753.
Therefore, the value of cos(tan(7/8)) is approximately 0.753.
