Francesca drew point (–2, –10) on the terminal ray of angle Theta, which is in standard position. She found values for the six trigonometric functions using the steps below. Step 1 A unit circle is shown. A ray intersects point (negative 2, negative 10) in quadrant 3. Theta is the angle formed by the ray and the x-axis in quadrant 1. Step 2 r = StartRoot (negative 2) squared + (negative 10) squared EndRoot = StartRoot 104 EndRoot = 2 StartRoot 26 EndRoot Step 3 sine theta = StartFraction negative 2 Over 2 StartRoot 26 EndRoot EndFraction = Negative StartFraction 1 Over StartRoot 26 EndRoot EndFraction = Negative StartFraction StartRoot 26 EndRoot Over 26 EndFraction cosine theta = StartFraction negative 10 Over 2 StartRoot 26 EndRoot EndFraction = Negative StartFraction 5 Over StartRoot 26 EndRoot EndFraction = Negative StartFraction 5 StartRoot 26 EndRoot Over 26 EndFraction tangent theta = StartFraction negative 2 Over negative 10 EndFraction = one-fifth cosecant theta = StartFraction 1 Over sine theta EndFraction = StartStartFraction 1 OverOver StartFraction Negative StartRoot 26 EndRoot Over 26 EndFRaction EndEndFraction = StartFraction negative StartRoot 26 EndRoot Over 5 EndFraction Secant theta = StartFraction 1 Over cosine theta EndFraction = StartStartFraction 1 OverOver Negative StartFraction 5 StartRoot 26 EndRoot Over 26 EndFraction EndEndFraction = StartFraction negative StartRoot 26 EndRoot Over 5 EndFraction cotangent theta = StartFraction 1 Over tangent theta EndFraction = StartFraction 1 Over one-fifth EndFraction = 5 Which of the following explains whether all of Francesca’s work is correct?
