(a) cos⁡270∘=\cos 270^{\circ}= □\square 0 Undefined (b) tan⁡270∘\tan 270^{\circ} Undefined (c) cos⁡540∘=\cos 540^{\circ}= □\square Undefined (d) tan⁡540∘=\tan 540^{\circ}= □\square Undefined (e) tan⁡−30∘=\tan -30^{\circ}= □\square Undefined

Studdy Solution
(a) cos⁡270∘=0\cos 270^{\circ}= 0 (b) tan⁡270∘\tan 270^{\circ} is Undefined (c) cos⁡540∘=−1\cos 540^{\circ}= -1 (d) tan⁡540∘=0\tan 540^{\circ}= 0 (e) tan⁡−30∘=−33\tan -30^{\circ}= -\frac{\sqrt{3}}{3}
