Interpretation of trigonometric graph
Interpretation of trigonometric graph of y = a sin x and y = a cos x. Amplitude is a indication of how much energy a wave contains. Graphs of y = a sin bx and y = a cos bx introduces the period of a trigonometric graph. Graphs of y = a sin(bx + c) and y = a […]
Trigonometric equation
the expression Rcos(x−α) and note that cos(x−α) can be expanded using an addition formula. Rcos(x −α) = R(cosxcosα +sinxsinα) = Rcosxcosα +Rsinxsinα Trigonometric eq
Trigonometric Equation
Transformed trigonometric equation adjusting their amplitude, period, phase shift, and vertical shift. Hence we have to find solution accordingly. Also we need to use GDC. Trigonometric equation
Applications of Sine and Cosine Rule
The sine rule and cosine rule . The sine rule is used when we are given either a) two angles and one side, or b) two sides and a non-included angle. The cosine rule is used when we are given either a) three sides or b) two sides and the included Sine and cosine rule
General solution of trigonometric Equati...
General Solutions of a Trig Equation. From the following diagram we see that sin( π -θ) = sin θ and cos ( -θ) = cos θ. General Solution of trigonometric eq
Sine Cosine and Area of triangle
Law of Cosines (also called the Cosine Rule) says: c2 = a2 + b2 − 2ab cos(C ). Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c … sine of angle B, and also equal to side c divided by the sine of […]
Trigonometric ratios conversion table
Pythagoras identities are use to convert trigonometric ratio from one form to another. Also we use right angle triangle for conversion. Conversion of trigonometric ratio
