There is one other version that you do not have access to.

Question statement

Evaluate each of the following, correct to 3 decimal places:

Don't forget the order of operations (BOMDAS)

Hint: Check mode of calculator, radians mode needed for some and degree mode needed for others.

Give any introductory information the student needs.

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$\frac{\cos(\var{num1[0]}^{\circ}) + \sin(\var{num1[1]}^{\circ})}{\tan(\var{num1[2]}^{\circ})}$

Unnamed gap

Advice

i) $\frac{\cos(\var{num1[0]}^{\circ}) + \sin(\var{num1[1]}^{\circ})}{\tan(\var{num1[2]}^{\circ})} = \var{ans1}$

ii) $\frac{\tan(\var{num2[0]}^{\circ}) + \sin(\var{num2[1]}^{\circ})}{\cos(\var{num2[2]}^{\circ}) - \sin(\var{num2[3]}^{\circ})} = \var{ans2}$

iii) $\frac{\cos(\var{num3[0]}) + \sin(\var{num3[1]})}{\tan(\var{num3[2]})} = \var{ans3}$

iv) $\frac{\sin(\var{num4[0]}) + \cos(\var{num4[1]})}{\tan(\var{num4[2]}) - \sin(\var{num4[3]})} = \var{ans4}$

Give a worked solution to the whole question.
