This in turn produces an unusual independence of mind, freeing the INTJ from the constraints of authority, convention, or sentiment for its own sake. INTJs are known as the Systems Builders of the types, perhaps in part because they possess the unusual trait combination of imagination and reliability.
Step 2 Use SOHCAHTOA to decide which one of Sine, Cosine or Tangent to use in this question. Step 3 For Sine calculate Opposite/Hypotenuse, for Cosine calculate Adjacent/Hypotenuse or for Tangent calculate Opposite/Adjacent. Step 4 Find the angle from your calculator, using one of sin-1, cos-1 or tan-1.
Since the cosine of $\angle C$ is the length of the side adjacent to $C$ divided by the length of the hypotenuse we have $$ \cos{(90 -a)} = \frac{|BC|}{|AC|}. $$ Thus $\sin{a} = \cos{(90-a)}$. The only property of $a$ that we have used in this argument is that it is one of the (non right) angles in a right triangle.he goal of this task is to provide a geometric explanation for the relationship between the sine and cosine of acute angles. In addition, students will need to think about the sine and cosine as functions of an angle in order to reason about when $\sin{a} = \cos{a}$. The picture is vital for both parts of this task.
