Because the radian is based on the pure idea of "the radius being laid along the ... At 0.01 radians both sin and tan are ... , Trigonometric Ratios in Radians; ... (sin 60 o /cos 60 o) = tan 60 o × tan 60 o = (√3) 2 = 3. Example 4: If sin θ = 2/3 and tan θ < 0, what is the value of cos θ? It is given that sin θ is positive and tan θ is negative. So θ must be in Quadrant II, where cos θ is negative. Now, sin θ = 2/3 = Opposite/Hypotenuse., Convert from Degrees to Radians 90 degrees. 90° 90 °. To convert degrees to radians, multiply by π 180° π 180 °, since a full circle is 360° 360 ° or 2π 2 π radians. 90°⋅ π 180° 90 ° ⋅ π 180 ° radians. Cancel the common factor of …, Learning Objectives. 1.3.1 Convert angle measures between degrees and radians.; 1.3.2 Recognize the triangular and circular definitions of the basic trigonometric functions.; 1.3.3 Write the basic trigonometric identities.; 1.3.4 Identify the graphs and periods of the trigonometric functions.; 1.3.5 Describe the shift of a sine or cosine graph from the equation of the function.
