Higher November 2023 Paper 1 Q29
29 Here are the equations of three graphs.
\(y = \sin x \qquad\qquad y = \cos x \qquad\qquad y = \tan x\)
(a) Which statement is true?
Tick one box. [1 mark]
- \(y = \sin x\) passes through \((180^\circ, -1)\)
- \(y = \cos x\) passes through \((180^\circ, -1)\)
- \(y = \tan x\) passes through \((180^\circ, -1)\)
- None of the graphs pass through \((180^\circ, -1)\)
(b) Which statement is true?
Tick one box. [1 mark]
- \(y = \sin x\) passes through \((270^\circ, 1)\)
- \(y = \cos x\) passes through \((270^\circ, 1)\)
- \(y = \tan x\) passes through \((270^\circ, 1)\)
- None of the graphs pass through \((270^\circ, 1)\)
