    Kwa mazoezi yafuatayo, pata thamani halisi ya maneno yaliyotolewa.

    39. \(\cos \frac{\pi}{6}\)

    40. \(\tan \frac{\pi}{4}\)

    41. \(\csc \frac{\pi}{3}\)

    42. \(\sec \frac{\pi}{4}\)

    Kwa mazoezi yafuatayo, tumia pembe za kumbukumbu ili kutathmini maneno yaliyotolewa.

    43. \(\sec \frac{11 \pi}{3}\)

    44. \(\sec 315^{\circ}\)

    45. Kama ni\(\sec (t)=-2.5,\) nini\(\sec (-t) ?\)

    46. Kama ni\(\tan (t)=-0.6,\) nini\(\tan (-t) ?\)

    47. Kama\(\tan (t)=\frac{1}{3},\) kupata\(\tan (t-\pi)\)

    48. Ikiwa\(\cos (t)=\frac{\sqrt{2}}{2},\) hupata\(\sin (t+2 \pi) .\) Kuna ufumbuzi mbili iwezekanavyo.

    49. Ni kazi gani ya trigonometric ni hata?

    50. Ni kazi gani ya trigonometric isiyo ya kawaida?
