The radius is always one on the surface of the cylinder and since it is a long cylinder, in the ideal world, the temperature is the same along the whole cylinder at each value of the angle theta. In the real non-idealized world, such problems are solved using numerical analysis …

Equation (13) can be used to find the maximum value for tan α in equation (8). First refractor (8) to isolate the φ terms by dividing the nominator and denominator of by cos θ cos dec and by using the tan x= sin(x)/cos(x) identity (three times): (14) Now substitute tan θ tan dec = cos φ and use the sin2φ+ cos2φ = 1 identity to get (15)

so tan(θ) = sin(θ)/cos(θ)) (trig identity #2 ) If we divide both sides of trig identity #1 by cos2(θ) then we have. or, since 1/cos is defined as secant, sec2(θ) = tan2(θ) + 1 (trig identity #3) This identity appears often in calculus courses. Other identities: sin(2θ) = 2 sin(θ) sin(θ) sin2(θ) = cos2(θ) =

Angle in degrees Tan ( 0 0 30 45 1 90 undefined Can you explain why the tangent at 90( is undefined? The ray at 90( is vertical, thus the slope is undefined. Part IV: General Practice. An angle of ( = 2(/3 is given. What is this angle in degrees? To convert to degrees we multiply the radian measure by 180(/(. Thus the degree measure is 2(180)/3=60.

the tangent of angle B, denoted tan(B) or tan B, is the ratio . the cotangent of angle B, denoted cot(B) or cotB is the reciprocal of tan B. We will focus on sine, cosine, and tangent in the class. It is, however, a good idea to have worked with the reciprocal functions a little bit.
