Step-by-step explanation:
Given the expression sin(cos^-1(5/6)-tan^-1(1/4)), to find the exact value of the expression, we need to first calculate the value in parenthesis i.e
cos^-1(5/6)-tan^-1(1/4)
= cos^-1(5/6)-tan^-1(1/4)
= cos^-1(0.8333)-tan^-1(0.250)
= 33.56 - 14.04
= 19.52
sin(cos^-1(5/6)-tan^-1(1/4)) = sin(19.52)
sin(19.52) = 0.3342
Hence the value of the expression sin(cos^-1(5/6)-tan^-1(1/4)). is 0.3342

The equation for the given line.
Solution:
If a line passes through two points, then the equation of the line is:
From the given graph it is clear that the line passes through the points (-1.5,0) and (0,1). So, the equation of the line is:
Therefore, the equation of the given line is
