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
Annuity
Annuities are an investment that provides a series of payments in exchange for an initial lump sum. With this calculator calculate several things The payment that would deplete the fund in a given number of years. The amount needed to generate a specific payment. The number of years your investment will generate payments at your […]
Properties of curve
derivative find (in general) points of inflection on the curve. If the graph of a function were a road map, these are the points on the curve where, instantaneously. Also use to find Maxima and minima. Properties of curve
Circle Theorem
Explore prove and apply important properties of circles that have to do with things like arc length, radians, inscribed angles. Circle Theorem
Procedure to prove identity and Solve tr...
Solving trigo equations proceeds by studying arc x on the trig circle and by using trig conversion table (or calculator). Hence use of calculator and table is must. Also we need know trigonometric plan. Further sign convention in quadrants also need to know. Trigonometric identities are true for all replacement values for the variables. Procedure
Double angle trigonometric Equation
Evaluate trig equations using the double angle formula. Also transformed double angle equation. Hence domain will be double. Double angle trigonometric equation
Double angle identity
Use the double‐angle identity to find the exact value for cos 2 x given that sin x = . Because sin x is positive, angle x must be in the first or second quadrant. The sign of cos 2 x will depend on the size of angle x. Double angle Identity
Trigonometric Identity
Worksheet of trigonometric identities . To prove that the left side is equal to the right side. Hence we have to use all six ratio their reciprocal. Also we have to use trigonometric relationship. As well as we use algebraic identity. Trigonometric identity
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
Human wants and scarcity
Scarcity refers to the basic economic problem, the gap between limited – that is, scarce – resources and theoretically limitless wants. Therefore This situation requires people to make decisions https://www.worldatlas.com/articles/what-is-scarcity.html
